I want to thank everyone for their help....Pimpin John, I'm not going to need any help from anybody doing my job, as I'm a successful business owner for 12 years now...why are you in this section if you have a problem with the question...please go away....

Temperature is an average measure of the heat energy of a substance. Temperature and heat are not the same thing (it took me a long time to understand this!).
Water boils (at sea level) at 212 degrees Fahrenheit. If you get a tiny drop on your arm, it won't hurt much, because a tiny drop can't contain a lot of heat. Get a pot of boiling water on your arm, and you will suffer a bad burn and much pain due to the much greater amount of heat contained.
Therefore, raising the temperature of a compound, element or material depends to a great extent upon its mass. If you add one calorie to an iceberg, you're not going to make the iceberg any warmer.

for example:
adding salt to water.... you increase its boiling point. The water can hold more heat before it boils. But adding the salt doesnt change the water temp untill you heat it.
Thermal Energy is the amount of heat a substance posses and Tempature is how hot (or cold) something is.
does that make sense?

You can't.
Thermal energy per particle is also called the average translational kinetic energy possessed by free particles given by equipartition of energy.
Thermal energy is the difference between the internal energy of an object and the amount that it would have at absolute zero. It includes the quantity of kinetic energy due to the motion of the internal particles of an object, and is increased by heating and reduced by cooling.

If it's at its temperature of melting or boiling, the thermal energy you add will cause it to change phase, but won't increase the temperature.

Only during a phase change. That way the energy is being expended creating the gas.

Will the Top Contributors help you years later on the job too? Do your own homework kids.
I don't think what you are asking is possible.

well and ice cube wouldn't increase the temperature

add heat while constantly draining it away with say water?

YUS
YOU CAN ADD HEAT TO
ALUMINUM FOIL WHILE NOT INCREASING,OR DECREASING TEMPURATURE :]
