Temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy from a higher temperature object to a lower temperature object. Temperature is a scalar quantity measured in degrees Celsius or Fahrenheit, while heat is measured in joules or calories.

Define heat energy?
Heat energy is the transfer of thermal energy between objects due to a difference in temperature. It flows from an object at a higher temperature to one at a lower temperature until thermal equilibrium is reached.
In your own words define the term heat?
Heat is a form of energy that is transferred between objects due to a difference in temperature. It flows from a warmer object to a cooler one to equalize their temperatures.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. Latent heat of vaporization is the amount of heat energy needed to change a substance from a liquid to a gas at its boiling point.
Can heat be an example of temperature?
Heat and temperature are related but not the same. Heat refers to the transfer of thermal energy between two objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance. Heat can cause a change in temperature, but they are different concepts.
Define thermal conductivity?
Thermal conductivity is a material property that describes the ability of a material to conduct heat. It is defined as the rate at which heat is transferred through a material per unit of thickness, area, and temperature difference. Materials with high thermal conductivity transfer heat more efficiently than materials with low thermal conductivity.
Define heat energy?
Heat energy is the transfer of thermal energy between objects due to a difference in temperature. It flows from an object at a higher temperature to one at a lower temperature until thermal equilibrium is reached.
In your own words define the term heat?
Heat is a form of energy that is transferred between objects due to a difference in temperature. It flows from a warmer object to a cooler one to equalize their temperatures.
Does gas form from heat?
Yes it does. But remember how you define 'heat': There are a lot of gasses existing on this planet at or even below room temperature, such as the air that you breathe.
Define 1 joule heat?
1 Joule heat is the the temperature of 1 g of water by 0.24 K. the typical energy released as heat by a person at rest, every 1/60th of a second.
Define isothermal expansion?
Isothermal expansion is what keeps gas at a constant temperature. It works by absorbing heat in order to conserve energy.
Define heat of compression and explain how it is computed?
Heat of compression refers to the increase in temperature that occurs when a gas or air is compressed. It is computed using the formula: Q = mCp(T2-T1), where Q is the heat of compression, m is the mass of the gas, Cp is the specific heat at constant pressure, T1 is the initial temperature, and T2 is the final temperature after compression.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. Latent heat of vaporization is the amount of heat energy needed to change a substance from a liquid to a gas at its boiling point.
Define endothermic and exothermic reaction in terms of sign of?
Endothermic are those which take heat so the sign of energy released will be negative and of change in heat is whcih is equal to heat of product - heat of reactant so in this case Hp - hR = -ve
Define heat and thermodynamics?
Heat is the transfer of energy between objects due to a temperature difference. Thermodynamics is the study of the relationships between heat, work, and energy, and how they affect the physical properties of matter. It encompasses principles such as the conservation of energy and the second law of thermodynamics.
Define heat of work and how it is computed?
Define Heat of Work and Explain how it is computed.Heat of Work (HOW) is the the amount of heat added to refrigerant during the compression process. The heat content of the refrigerant at the outlet of the compressor (high-side) is subtracted from the heat content at the inlet of the compressor (low-side). The unit of measurement is in Btu/lbAnswerThere is no such thing as 'heat of work'. Heat and work are two different, but related, things. 'Heat' describes energy in transit from a higher temperature to a lower temperature, whereas 'work' describes energy in transit when one form of energy is converted into another form. The difference between work and heat is a measure of the rise in the internal energy of an object.
What best describes the relationship between heat and temperature heat and temperature are the same thing heat changes temperature heat is a measure of temperature or temperature measures?
Heat and temperature are related but not the same thing. Temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy between objects due to a temperature difference. Heat can change the temperature of an object by transferring energy to it.
Is heat the temperature of a reaction?
No, heat is an energy where the temperature is not.
