Question

What amount of heat is required to raise the temperature of 25 grams of copper to cause a 15º C change? The specific heat of copper is 0.39 J/gº C.

115 J

150 J

250 J

300 J

Answer 1

the answer is 150 J , your welcome

Answer 2

`Q = 150 J`

Step-by-step explanation:

Heat required to raise the temperature of the object is given as

`Q = m s \Delta T`

here we know that

m = mass of the object

m = 25 grams

s = specific heat capacity of the object

`s = 0.39 J/g ^oC`

`\Delta T` = temperature change

`\Delta T = 15^o C`

now we know that

`Q = 25 * 0.39 * 15`

`Q = 150 J`
