Question

The thermal energy used by heater in 3 minutes is used to melt wax.Melting point of solid wax is 60.Specific heat of wax is 220j/g.Heater supplies 7700j of energy,how much wax melts?

Answer 1

m = 35 g

Step-by-step explanation:

The specific heat of a material can be calculated by the following formula:

`C = (Q)/(m)\\`

where,

C = Specific Heat of Wax = 220 J/g

Q = Amount of Heat Supplied by the Heater = 7700 J

m = mass of wax melted = ?

Therefore,

`220\ J/g = (7700\ J)/(m)\\\\m = (7700\ J)/(220\ J/g)\\`

m = 35 g
