Temperature Formula And Examples

Temperature Formula :

Temperature Formula is difference ∆T(c) in Celsius is equal to the amount of heat absorbed or released Q(J) in joules divided by the mass of the body m (g/kg/t) in gram, kilogram and tone and specific heat of the body c(j/kg) in joule kilogram degree Celsius. Hence Temperature Formula can be written as

∆T(c)=Q(J)/m (g/kg/t)*c(j/kg)

∆T → temperature difference in Celsius

Q → amount of heat absorbed or released in joules

m → mass of the body in gram (g), kilogram (kg) and tone (t)

c → specific heat of the body in J/kg

Sample Examples :

Example 1:

Calculate the temperature if 300J of heat is released by the body of mass 6 kg and has a specific heat of 0.8 J/Kg0 C ?

Solution :

Given,

Heat released Q=300J

Mass m=6kg

Specific Heat c=0.8 J/Kg0 C

The temperature is given by ∆T=Q/mc

=300/6*0.8

=300/4.8

=62.5

∆T=62.50c

Example 2:

Calculate the heat released when the temperature changes by 800 C by a body of mass 5 kg which has a specific heat of 0.9J/ Kg0 C?

Solution :

Given,

Temperature change =800 C

Mass=5Kg

Specific heat c=0.9J/ Kg0 C

The Heat released is given by formula Q=mc∆T

=5*0.9*80

Q  =360J
