Calculate the amount of heat energy required to raise the temperature

1.	Calculate the amount of heat energy required to raise the temperature of 100 g of copper from 20°C to 70°C. specific heat capacity of copper = 390 J kg-1 K-1.
Answer» Mass of copper m = 100 g = 0.1 kg Change of temperature Δt = (70 − 20)^oC Specific heat of capacity of copper = 390 J kg^-1K^-1 Amount of heat required to raise the temperature of 0.1 kg of copper is Q = m × Δt × c = 0.1 × 50 × 390 = 1950 J

Calculate the amount of heat energy required to raise the temperature of 100 g of copper from 20°C to 70°C. specific heat capacity of copper = 390 J kg-1 K-1.

Answer»

Mass of copper m = 100 g = 0.1 kg

Change of temperature Δt = (70 − 20)^oC

Specific heat of capacity of copper = 390 J kg^-1K^-1

Amount of heat required to raise the temperature of 0.1 kg of copper is

Q = m × Δt × c

= 0.1 × 50 × 390

= 1950 J

In an industrial process 10 kg of water per hour is to be heated from `20^@C` to `80^@C`. To do this steam at `150^@C` is passed from a boiler into a copper coil immersed in water.

How many kilograms of steam is required per hour (specific heat of steam`=1 cal//g^@C`, Latent heat of vapourization`=540 cal//g`)?
Water at `0^@C` was heated until it started to boil and then until it all changed to steam. The time required to heat water from `0^@C` to `100^@C` is 5 min and the time to change boiling water to steam is 28 minutes.
