How do the two temperature curves relate to each other?
Answers
Answer:
Imagine that you have a block of ice that is at a temperature of -30°C, well below its melting point. The ice is in a closed container. As heat is steadily added to the ice block, the water molecules will begin to vibrate faster and faster as they absorb kinetic energy. Eventually, when the ice has warmed to 0°C, the added energy will start to break apart the hydrogen bonding that keeps the water molecules in place when it is in the solid form. As the ice melts, its temperature does not rise. All of the energy that is being put into the ice goes into the melting process and not into any increase in temperature. During the melting process, the two states – solid and liquid – are in equilibrium with one another. If the system was isolated at that point and no energy was allowed to enter or leave, the ice-water mixture at 0°C would remain. Temperature is always constant during a change of state.
Continued heating of the water after the ice has completely melted will now increase the kinetic energy of the liquid molecules and the temperature will rise. Assuming that the atmospheric pressure is standard, the temperature will rise steadily until it reaches 100°C. At this point, the added energy from the heat will cause the liquid to begin to vaporize. As with the previous state change, the temperature will remain at 100°C while the water molecules are going from the liquid to the gas or vapor state. Once all the liquid has completely boiled away, continued heating of the steam (remember the container is closed) will increase its temperature above 100°C.

when water is at 0°C, can it be a solid, a liquid, or both a solid and a liquid?
Answers
At zero degree Celsius water starts freezes to ice. But the melting point of water is zero degree itself. Hence, if the ice is kept at room temperature it starts to melt. Thus, there will be both solid and liquid.
What is freezing point ?The freezing point of a substance is the temperature at which its liquid state converts to solid state. The freezing point of a substance depends on the bond type, molar mass, temperature and pressure.
The freezing point of water is 0°C. Hence, from 0°C, liquid water starts to freeze to form ice. If the ice at this temperature kept at room temperature, it starts to melt.
If the water is kept at the 0°C itself there will be ice only. If the temperature changes in surroundings, the ice starts to melt. Hence, there will be both ice and liquid water till the ice completely melt.

Which group did the Emancipation Proclamation primarily concern?
A)slaves working in the Union army camps
B)slaves belonging to Confederate soldiers
C)slaves living in Confederate states
D)slaves living in Kentucky, Maryland, and Delaware
Answers
Answer:
C.
Explanation:
I hope this is correct Have A Nice Day :)
The Emancipation Proclamation was a presidential decree issued by President Abraham Lincoln on January 1, 1863, during the American Civil War. Hence option C is correct .
Who did the Emancipation Proclamation primarily concern?The primary purpose of the Emancipation Proclamation was to declare that all slaves living in Confederate states were henceforth free.
Therefore, the correct answer to the question is C) slaves living in Confederate states. The Emancipation Proclamation did not apply to slaves living in Union states, nor did it apply to slaves living in Kentucky, Maryland, and Delaware, which were slave states that remained loyal to the Union.
The Emancipation Proclamation was a significant turning point in the Civil War because it changed the nature of the conflict from a war for the preservation of the Union to a war for the abolition of slavery.
While the Emancipation Proclamation did not free all slaves immediately, it paved the way for the Thirteenth Amendment to the United States Constitution, which formally abolished slavery throughout the entire country .

How did the Cold War heighten American fears of Communism?
Answers
Answer: Well...
Explanation:
A very large concern during the cold war was the chance of there being a nuclear war. Both the Russians and Americans held control of the majority of nuclear warheads existing at the time, and naturally, with the Soviet Union being a communist nation, this reflected negatively on communists in the American public.
Another reason was during the cold war, Cuba was taken over into a communist rule. Considering Cuba was right on the US's doorstep, they potentially could launch missiles at Washington DC.

How might life in East Africa have been different if the people there had not accepted the presence of Muslim traders?
