Answer:
Touching a stove and burning your your hand
Explanation:
Conduction is one of the three methods of heat transfer (the others being convection and radiation). Conduction involves the transfer of heat via direct contact with a solid medium. In conduction, heat or thermal energy moves from the hotter region to the colder region.
In this question, an example of conduction is the act of "Touching a stove and burning your your hand". The stove is acting as the solid medium here, with the heat being transferred from the hot object (stove) to the less hot one (hand) via touch (direct contact).

Step 6: Measuring the Volume of Air Near 40°C
Temperature of gas: 40
COMPLETE
Height of the column of gas: 6.7
cm
Volume of gas (V =)
Temperature of gas: 303K
help me find out how to get the volume !!! pleaseeee
The volume using the cylinder formula : V=πr²h
Further explanationCharles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]
This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume
If a certain amount of gas is heated, the volume will increase
So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable
Because the tube is cylindrical, to find the volume using the cylinder formula
[tex]\tt V=\pi.r^2.h[/tex]
Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2
Answer:
1. Temp of gas 40C, Height of the column of gas 6.7
2. Temp of gas 313K, Volume of gas 0.84

The size of an atom would be described in _______.
Answer:
atomic radius
Explanation:
so radius
Answer:
Explanation:
The average size of an atom is about 100 picometers or one ten-billionth of a meter. Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons. The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes.

why is the symbol [Ar] used in the electron configuration of potassium, and what does it represent?
Answer:
To denote a stable inner configuration and it represents argon
Explanation:
The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.
This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.
Ar is Argon with a configuration of 1s² 2s² 2p⁶ 3s² 3p⁶So, this configuration is stable and it the inner configuration of potassium excluding the outermost orbitals.Susie is in the kitchen making brownies.

. Find the mass of 2.61 moles of H2O2.
Mass of H₂O₂ = 88.778 g
Further explanationThe mole itself is the number of particles contained in a substance amounting to 6.02.10²³
Mole can also be determined if the amount of substance mass and its molar mass is known
[tex]\large {\boxed {\boxed {\bold {mol = \frac {mass} {molar \: mass}}}}[/tex]
moles of H₂O₂ = 2.61
So the mass of H₂O₂(MW=34,0147 g/mol) :
[tex]\tt mass=mol\times MW\\\\mass=2.61\times 34,0147 g/mol\\\\mass=88.778~g[/tex]

Answer:
particle E and R
Explanation:
isotopes = atoms of same element with same proton number but different number of neutron
nucleon number = proton number + number of neutrons
particle E
- nucleon number = 16
- proton number = electron = 8
- number of neutrons = 16-8 = 8 ✅
particle Q
- nucleon number = 18
- proton number = electron = 9
- number of neutrons = 18-9 = 9
particles R^2-
- nucleon number = 18
- proton number = 10-2 = 8
- number of neutrons = 18-10 = 8 ✅
particle T^+
- nucleon number = 22
- proton number = 10+1 = 11
- number of neutrons = 22-11 = 10
how many electrons elements are present in period 2 ?
what is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?
Answer: double displacement
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation is:
[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]
Thus as ions get exchanged , it is double displacement reaction.
Under which conditions does a real gas behave most like an ideal gas? A. At low temperatures and high pressures B. At low temperatures and low pressures C. At high temperatures and high pressures D. At high temperatures and low pressures
Answer: D. At high temperatures and low pressures
Explanation:
At low temperature and high pressure, the kinetic energy of gas molecules is negligible and molecules will have negligible forces of attraction. So real gases will behave least like an ideal gas under such conditions.
At high temperature and low pressure, energy due to intermolecular forces becomes less important in comparison to the kinetic energy of particles. The size of molecules also become less significant than the empty space between the gas molecules. So real gases behave in a similar manner to ideal gases at high temperature and low pressure.
Which statements are true about stars smaller than the sun? They have longer lifespans. They consume their hydrogen fuel slowly. They use helium, not hydrogen, as fuel. They are more luminous than the sun.
Answer:
The answer is "They have longer lifespans" and "They consume their hydrogen fuel slowly"
Explanation:
A star is a galactic item comprising of luminous spheroid of plasma held together by its own gravity. The closest star to Earth is the Sun. Numerous different stars are obvious to the unaided eye from Earth during the night, showing up as a large number of fixed radiant focuses in the sky because of their gigantic separation from Earth.
For the vast majority of its dynamic life, a star sparkles because of atomic combination of hydrogen into helium in its center, delivering energy that navigates the star's inside and afterward transmits into space. Practically all normally happening components heavier than helium are made by heavenly nucleo-synthesis during the star's lifetime, and for certain stars by supernova nucleo-synthesis when it detonates. Close to the furthest limit of its life, a star can likewise contain degenerate issue
A star's life starts with the gravitational breakdown of a vaporous cloud of material made essentially out of hydrogen, alongside helium and follow measures of heavier components. At the point when the heavenly center is adequately thick, hydrogen turns out to be consistently changed over into helium through nuclear fusion, producing energy all the while.
