What else can I help you with?
Which substance would you expect to heat up most quickly?
A substance with low specific heat capacity and low thermal conductivity would heat up most quickly because it requires less energy to raise its temperature and does not distribute heat effectively. Materials like metals and low-density liquids generally heat up quickly compared to dense solids with high specific heat capacities.
What is the total kinetic energy of the particles that make up a substance?
Heat
The particular rate at which a material warms up upon absorbing heat is a what property that can be used to identify a substance?
Specific heat capacity is the property that describes the rate at which a material warms up upon absorbing heat. It can be used to identify a substance based on how quickly or slowly it heats up compared to other materials.
Why do substance expand when heat energy is added to them?
Heat is a measurement of the amount of motion (or kinetic energy) of the particles of which a given substance is composed. In a solid, this motion is just a vibration, since the particles remain in place. When particles vibrate more, they will take up more space. In a gas, the particles move independently of each other, and if they move faster, they will exert more pressure and thus will tend to expand.
Is it heat capacity is extencive or intensive?
anything that is "specific" is intensive. look at the units: J/(kg °K)that is, it doesnt depend on the quantity available.with "specific" properties, you multiple by the amount you want and you get the total amount of that property.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
How does heat depend on a mass of a substance?
The heat depends on the mass of a substance as there are more particles to heat up. When one particle is given energy from the heat, it moves around on it's fixed point (in a solid). When it touches the next particle, the energy is passed along warming the object up right the way through. This is called conduction.
Is density is a measure of how much heat there is in a volume of a substance?
"Any object, wholly or partially immersed in a stationary fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." (Archimedes) And this is independent on the heat.
Which warms up slower and holds it heat longer water or land?
Given equal volumes and equal temperature changes without any change of state, no substance requires as much heat for a given temperature increase or expels as much heat during the equivalent temperature decrease than water.
When heat is transferred to a substance describe why the temperature goes up?
The best answer is: Because heat has been transferred to the substance, and it now contains more of it.
What is it called when heat breaks up a substance?
Thermal Decomposition
What do you call that does not conduct heat?
it will heat up more more
What happens if heat transfers through a graduated cylinder?
Well that depends, if you have substance within the cylinder, then the substance will begin to heat up due to the transfer of heat. But if you don't have anything within the cylinder then the cylinder will heat up on its own and might melt if you apply enough heat.
What turns solids in to liquid?
Solids turn into liquids when you melt or heat- up the substance for a curtian amount of time. If you boil or 'heat up' the substance for too long than it may turn into a gas.
Which substance would you expect to heat up most quickly?
A substance with low specific heat capacity and low thermal conductivity would heat up most quickly because it requires less energy to raise its temperature and does not distribute heat effectively.

What is the total kinetic energy of the particles that make up a substance?
Heat
Why does the volume heat up a substance?
it doesn't it raises the average energy a particle has. that's temperature not heat.
