Distinguish between heat and temperature
Plz write 6 points for each heat and temperature....
Answers
Answer:
Heat( Q ) vs Temperature( T )
1 Heat is the energy stored inside an object
1 Coldness or hotness of an object is measured by Temperature
2 The SI unit of heat is Joules
2 The SI unit of temperature is Kelvin
3The amount of heat energy contained in an object depends on its mass, temperature, and material which is the specific heat capacity.
3 The Temperature of a body depends on the average kinetic energy of its molecules or particles.
4 The Heat can be measured using the principle of calorimetry or the principle of the method of mixtures.
4 The temperature is measured using the thermometer.
5 Two bodies that have a similar amount of heat energy can differ in their temperature
5 Two bodies at a similar temperature can contain different amounts of heat energy.
6 When two bodies are in contact, the total amount of heat energy is the sum of the heat energy of each object.
6 If two objects are at completely different temperatures are kept in contact, the resultant temperature will be the temperature between the two temperatures.
7 Heat has the ability to do work.
7 Temperature can be used only to measure the degree of heat.
8 Heat is the measure of how many molecules are in an object multiplied by how much energy each molecule possesses.
8 Temperature is related to how fast the molecules move within the object.
9 The heat flows from hotter bodies to colder bodies.
9 The temperature increases when heated and it decreases when cooled.
HEAT:
•it is the form of internal energy* obtained because of the random motion and the attractive force of molecules within the substances.
•Its SI unit is Joule
•The amount of heat energy contained in a body depends on its mass,temperature and material.(specific heat capacity)
•It can be measured using the principle of calorimetry(or principle of method of mixture)
•Two bodies that have same amount of heat energy can differ in their temperature.
•When two bodies are in contact, the total amount of heat energy is the sum of the heat energy of each body.
TEMPERATURE:
•It is a quantity that determine which direction the heat will flow in.
•Its SI unit is Kelvin.
•The temperature of the body depends on the average kinetic energy of its molecule.
•It is measured using a thermometer.
•Two bodies at the same temperature can contain different amount of heat energy.
•If two bodies at different temperature are kept in contact, the resultant temperature will be the temperature between the two temperatures.
*Internal energy is sum of potential and kinetic energies of the body.
