A substance that has a low specific heat needs less heat to increase its temperature. In other words under a constant heat flux it will heat or cool more quickly than the higher specific heat substances.

Will things that heat quickly have a low or high specific heat?
both
What are the uses of substances that are good conductors of heat?
cooking utensils, heat from the fire can reach the food more quickly.
How does a substance with low specific heat cool down or heat up?
I think slowly because a substance that heats up quickly have a high specific heat capacity. i think slowly Specific heat is that amount of energy needed to raise a unit mass by a unit temperature. If something has a high specific heat, it means it needs a lot of energy to heat up, meaning slow.
Does a high specific heat allow water to heat slowly cool slowly or to do both?
I think the answer is cool slowly because if you left something that was hot out, it would cool.
What happens to the amount of radiation a radioactive substance emits when you heat it up or cool it down?
when you heat up or cool down radioactive substances, nothing changes how much radiation it emits.
Do different liquids cool at different rates?
There are two issues: specific heat and thermal conductivity.Specific heat is a measure of how much heat it takes to make a temperature change in a substance. If liquid A has a smaller specific heat than liquid B, then A will experience a bigger temperature change on gaining or losing a given amount of heat energy. Water has a greater specific heat than most substances, so it takes a lot of heat to make a large temperature change (or, to think of it the other way, it has to lose a lot of heat to cool down). That would make it tend to cool more slowly than other substances (all other things being equal).Thermal conductivity is a measure of how fast heat is dispersed through a sample. If a substance has a high thermal conductivity, then heat moves quickly through the substance. Water also has a high thermal conductivity for a liquid, so as the edges of a sample of water (where it contacts the air or container) cool down, heat moves from the inside to the edges quickly. That would make it tend to cool more quickly than other substances (all other things being equal.)
Metallic substances have higher specific heat capacities than nonmetallic substances?
yes metallic substances have higher specific heat capacities
Does the atmosphere allow heat to escape quickly in order to cool the planet?
No the atmosphere does not allow heat to escape quickly to cool the planet
What property of a surface determines how quickly or slowly it will heat and cool?
The thermal conductivity and color of a surface determines how quickly or slowly it will heat and cool
Why does water not heat up or cool as quickly as air?
Because the specific heat of water is very high. In fact, water has about 1400 times more heat carrying capacity than air.
The absorption of heat by any substances is dependent upon?
its specific heat capacity

Does a substance that cools off quickly have a high or low specific heat capacity?
Specific heat capacity is the amount of energy required to increase the temperature of an object or substance by 1oK. The rate at which something cools is proportional to the difference in temperature between the object and its surroundings. Consequently, neither has any relation to the other.

Explain why substances with hig specific heats take longer to heat up than substances wit the same mass which have low specific heats?
Type your answer here... A substance with high specific heat means it can absorb alot more heat energy before its temperature increases. A substance with low specific heat cannot absorb alot of heat energy so its temperature increases quickly because it cant absorb the heat. Remember there is a difference between Heat energy and Temperature. The ocean can absorb alot of heat energy but still feel like its cold in temperature. The tip of a needle can be at 1000 degrees temperature but there is hardly any actual heat energy in it because its so small.
