Question

what is heat
Heat is a form of energy obtained due to random motion of molecules in a substance. S.I unit if heat is joule ( J ) . Heat is measured by principle of calorimetery​

Answer 1

Answer:

In thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter.The various mechanisms of energy transfer that define heat are stated in the next section of this article. It Heat is the form of energy that is transferred between two substances at different temperatures. The direction of energy flow is from the substance of higher temperature to the substance of lower temperature. Heat is measured in units of energy, usually calories or joules. Heat and temperature are often used interchangeably, but this is incorrect. Temperature is the measure of hotness or coldness of matter. Stated another way, temperature is the average kinetic energy per molecule of a substance. Temperature is measured in degrees on the Celsius (C) or Fahrenheit (F) scale, or in kelvins (K). In simplest terms, temperature is how hot or cold an object is, while heat is the energy that flows from a hotter object to a cooler one. For example, the temperature of a cup of coffee may feel hot if you put your hand around it. It is hot because heat from the coffee is transferred to the cup.

Hope it helps u my frnd !!!
