Question

How many joules of heat are needed to raise the temperature of 50.0 g of aluminum from 10°C to 110°C, if the specific heat of aluminum is 0.95 J/g°C?

Answer 1

Heat required to raise the temperature of the aluminium is 4750 J

Step-by-step explanation:

As we know that the heat energy required to raise the temperature of the aluminium is given as

`Q = ms\Delta T`

here we know that

m = 50 g

`\Delta T = 110 - 10`

`\Delta T = 100 ^oC`

so we have

`Q = 50(0.95)(100)`

`Q = 4750 J`
