General Chemistry

Question #118883

Determine the number of joules required to warm a 375 g sample of steam at 116.0 °C to
213.0 °C.

Expert's answer

The specific heat of steam is 2.010 kJ⋅°C-1kg-1

Mass = 0.375 kg

Change in temperature = (213-116) °C

=87°C

So required heat = 0.375 × 2.01×87

= 65.57 J
