Why is a great deal of heat needed to raise the temperature of water by a given amount?
because it has a great heat capacity
Does metal with high heat capacity raise temperature of water more than a metal with low heat capacity?
yes
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
Is it harder to raise the temperature of a rock than it is to raise the temperature of water?
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.

How can you change ice into water?
The best way is to remove heat by cooling.

What is the specific heat of a substance?
The amount of heat a substance can hold.
Why is water an excellent material to use in a calorimeter?
Water is an excellent material to use in a calorimeter because it has a very high specific heat, making it very hard for water to raise its temperature even by 1 degree celsius, but as hard as it was to raise the temperature of the water, it is equally as hard to lower the temperature of the water-making it able to effectively retain heat and allowing the other material inside of the calorimeter to absorb that heat.
Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
Which common substance requires the most heat to raise the temperature of a gram by 1 degree Celsius?
water
Heat needed to raise the temperature of one gram of water one Celsius degree?
This is one calorie
