Question

Write an essay - 5 paragraphs that explain the difference between:

1. Thermal Energy
2. Temperature
3. Heat
4. Specific Heat

Give examples for each element so it concludes the paragraphs

Answer 1

THERMAL ENERGY - It is form of inergy due to molecular motion of kinetic energy .Thermal energy is basicly associated with temperature . If temperature increases then thermal enrgy of body also increases .Degree of hotnes nad coldness of abody decided by content of thermal energy inside a body .

its si unit is joule . it is scalre quantity .

TEMPERATURE - Temperature is basicly parameter which decide hotness and coldness of body . If temperature increases then body become hot . If body release some heat then temperature decreases .

it is also a scaler quantity . it is measured in different scale

its si unit is kelvin .

HEAT - Heat is a form of energy which flow from one body to another body due to temperature difference .

Bwsicly stored energy due to molecular motion is thermal energy but part of thermal energy that flow from one body to another body due to temperature difference is heat .

When some heat added to a body then its temperature increases .

heat is scaler quantity with si unit joule

SPECIFIC HEAT - It is amount of heat required to increase the temperature of one unit mass of body by one degree celsius .

it is of two type

i - specific heat at constant volume - if heat added at constant volume .

ii specific heat at constant pressure - if heat added at constant pressure .
