15000 joules is used to heat a 950g piece of metal from 45 degrees Celsius to 78 degrees Celsius what is the specific heat of this metal

0.478 J/g/C

Explanation:

When solving questions on heat energy, we can use the formula

Q = mcT where

Q is the amount of energy supplied in Joules

m is the mass of the object in Grams

c is the specific heat capacity of the metal in Joules Per Gram Per Degree Celcius

T is the change in Temperature in Degree Celcius.

So by applying the formula to this question, we get:

15000 = (950) (c) (78 - 45)

c = 0.478 J/g/C
