2520J/((70.0°C-10.0°C)*10.0kg*1000g/kg)
=0.0042 J/gC°

Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
When a liquid is heated does the energy of it increase?
When you add energy to a substance it's temperature will remain constant if there is a change of state from solid to liquid or liquid to gas. The energy added is absorbed in changing state; known as latent heat of fusion (melting), or latent heat of vaporization. For some substances a similar effect can occur if there is a chemical change. There are also situation where an influx of energy will cause a decrease in temperature. One such is drinking water stored in a canvas container. Sunlight causing the wet canvas to evaporate some of its water will effect a decrease in the temperature of the stored water.
What happens to thermal energy when temperatures increase?
When the temperature of a material increase, thermal energy is added to the material. It also increases the kinetic and potential energy of the particles. When the temperature reach the boiling or melting point, the kinetic energy stays the same, but the thermal energy and the potential energy still keeps adding and increasing. And when ONLY the potential energy increase, the state of the material changes from one to another.
What happens to the volume of gas or liquid s the temperature of a gas or liquid increases?
When heat is added to the system, we increase the average kinetic energy of molecules making up that system. When we increase the temperature, molecules undergo more rapid collisions and therefore takes up more volume. Molecules in solid state of matter has the least kinetic energy.
Can thermal energy be added without an increase in temperature?
No, thermal energy is entirely energy added for heat.
How much energy must be added to 1 kilogram piece of aluminum with a specific heat of 900 J to increase its temperature from 20 degrees Celsius to 100 degrees Celsius?
90,000

To increase.
What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
What happens to temperature when energy is added as heat?
Either the temperature will increase, or it will remain the same. In the latter case, there is a phase change, as when ice melts.
What happens to molecules as energy is added and the temperature increases?
what happens to molecules as energy is added the temperature increses
As heat energy is added to a liquid do the particles increase or decrease in movement?
As heat energy is supplied to a liquid, its temperature rises. The rise of temperature causes a rise in the kinetic energy of the particles; which happens when the speed of the particles increases.
How the temperature of water changes when sugar is added to it.?
The temperature increase a bit.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What happens to the water temperature when calcium chloride is added?
Temperature would increase

What happens if you put heaps of energy (heat) into a liquid?
The liquid's temperature will increase. If enough heat is added, it will eventually evaporate.
