DEfine One Joule in terms of Heat energy..viz..ONE JOULE is the HEAT ___ by body of mass__to raise it temp by ___

Heat is one of the many forms of energy and it is measured
in Joules.

If you want to measure the amount of heat needed
to heat an object, you could use the followings as refference: 1 gram of water is heated
to 1 Celsius degree. The amount of heat needed is of 4.2
Joules.

If you want to determine how many Joules are needed
to heat 1 kg of water to 10 Celsius degrees, you'll have to use the rule of
three.

1g water........1C degree...............4.2
Joules

1000 g...........10C degrees.............x
Joules

We also know that 4.2 Joules are equivalent to one
calorie.

If you want to determine how many Joules are
needed to transform the mass of a substance from a liquid to a gas, you'll have to use
the formula:

Q = mCdeltaT

m -
themass of the substance

C- the specific heat of the
substance

delta T - the change in temperature (T
