 P1 Heat & Temperature 

Syllabus Summary Questions Answers

 
Temperature 

  Temperature is a measure of how hot or cold a body is. 

  Temperature is measured by a thermometer.

  Heat

  Heat is a form of energy.

    Heat energy flows from a hot object to a cold object. 

   The bigger the temperature difference between a body and its surroundings, the faster the

       rate at which heat is transferred.

  Specific heat capacity

  Specific heat capacity is the amount of energy needed to raise the temperature of a one kilogram

     substance by 1 ºC.

   Energy transferred = mass x specific heat capacity x temperature change 

  Specific latent heat

  Specific latent heat is the amount of energy needed to change the state of one kilogram of a

     substance without a change in temperature.

   Energy transferred = mass x specific latent heat
