Some of the heat from the warm earth is trapped by greenhouse gases in the atmosphere, where it adds to the warming of the earth. The rest of the heat escapes into space.

How do electrons help in transfer of heat energy?
when a substance is heated,the molecules in that substance get heat energy. we know that all of the molecule in the substance having electrons. when substance is heated. electrons becoming high energetic.and they move faster and also energy will propagate though out the substance
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
What would increase a temperature of a substance?
When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.
When a pure substance is heated or cooled but does not change state the energy as heat is the what?
chemical change
When a substance is heated it must gain electrons and energy?
Yes, it gains kinetic energy, for instance, when water is heated into water vapours the molecules of water vapour move faster than the molecules of water. This is because the water vapour has more kinetic energy than water.

What happen to the average energy of the molecules in a substance when it is heated?
They increase in energy.
When a substance is blank it gains thermal energy?
heated
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
What are the changes in the kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
When a substance is heated and the average kinetic energy remains low where has the energy gone?
If a substance is heated, it will either get hotter, or it will change its phase - for example, when ice at 0 degrees Celsius is melted to water at 0 degrees Celsius. In this case, the heat energy is converted to a type of potential energy.
Why does the substance in the column of the thermometer go up when it is heated?
The substance expands - and the tube (column) constrains it to go upwards.
What should be used to remove heated to heated objects?
When a substance is heated up, it emit heat radiation. In such way substance keep on losing heat energy. Thus a way that increase heat losing can lower heat of substance. Water can used as heat absorber.
