If the specific heat of methanol is 2.51 j/k-g, how many joules are required to raise the temperature of 50 g of methanol from 20oc to 70oc?

The amount of heat required is 6275 J

Explanation:

To calculate the change in temperature, we use the equation:

where,

q = heat absorbed = ?

m = mass of methanol = 50 g

c = specific heat capacity of methanol = 2.51 J/g.K

= change in temperature =    (change remains the same)

Putting values in above equation, we get:

Hence, the amount of heat required is 6275 J
