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.
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 the number of layers of insulation affect how quickly the water cools down?
yes it will cool down slower as the heat cannot get to the water as easily
Why does a hot cup cool down more quickly from 80degrees-60degrees than 60degrees-40degrees?
Since temperature falls off exponentially, the temperature falls quickly initially and then at a slower rate.
What is mechanisms to cool the body down?
sweat is a mechanism to cool the body down. the body creates sweat, so it can cool itself down.
When a substance evaporates does it cool down or warm up?
It has to warm and then cool.
How do you quickly cool down porridge?
Blow it!
What substance could be used to cool down a road to reduce the temperature?
The substance that could be used to cool down a road to reduce its temperature is light-colored bitumen.
What causes a substance to cool down?
A substance becomes cold by radiating its heat out to its surrounding.
How can you cool down your anger quickly?
count to ten and breath
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.)

Why is there a difference in time taken for different materials to cool down after being put into a beaker of hot water?
specific heat capacity is the amount of energy you have to put into a substance to raise a kg of it by 1 degree C or K. because the specific heat capacity is different for different materials, and because the flow of heat out of materials into the water is related to the temperature differencebetween the water and the objects, assuming objects placed in water have same initial temp, the objects with the higher specific heat capacities will cool less quickly.
What rock have crystal in?
All rocks have crystals in them, what ever king they are. If they cool down slowly they tend to have bigger ones and if they cool down quickly they have smaller ones. SIMPLES!!
What is the effect of clear skies on a desert?
The lack of clouds means that the desert will heat up quickly when the sun rises but will also cool down quickly when the sun goes down.

What happens when gas cool down?
When cooled enough it will condense into a liquid. The required temperature changes with the substance.
