Which metal has a higher specific heat than copper?
Explanation: Lower specific heat means less resistance to change. Aluminum has a specific heat capacity more than twice that of copper. If equal amounts of heat are given to equal masses of aluminum and copper, the metal that more rapidly increases in temperature is
What is the specific heat capacity of a substance?
The specific heat capacity describes not only the relationship between heat input and temperature increase when a substance is heated, but also for the case when a substance is cooled. In this case, the specific heat capacity provides the relationship between a release of heat and the resulting temperature decrease.
What is high specific heat capacity of water used for?
The high specific heat capacity of water is used, for example, in central heating systems. The temperature of the water in the radiator decreases only slightly when releasing heat to the surroundings. As a result, the radiator remains hot for a relatively long time.

What is the ability of a substance to absorb energy?
The ability of a substance to absorb energy depends upon both microscopic (molecular/atomic) and macroscopic (phase, temperature, pressure) considerations. It can get quite involved. For example water will have different heat capacities for all three phases (ice, liquid and gas).
What is specific heat?
Remember, specific heat is for the whole substance when you are talking about a solution. Obviously, each component will contribute, but you are not changing the specific heat capacity of pure water when you dissolve salt or sugar or whatever into it, you are creating a solution that has its own heat capacity.
How much more water is needed for temperature regulation?
But this tiny difference is much more expensive than, say, adding 1.4% more water to your temperature regulation system. Water is a major benchmark when comparing specific heat capacity, as the (non-metric) calorie is defined as the amount of energy needed to increase the temperature of 1g of water by 1 degree Celsius.
What causes changes in temperature?
Changes in a material's temperature or state of matter are caused by changes to the internal energy. The energy required by different materials depends on their 'heat capacity' and 'latent heat'.
