Respuesta :
c = 200 j/g*C
m = 2g
ΔT = 55 - 35 = 20C
Heat = mcΔT = 2 * 200 * 20 = 8000J = 8kJ
m = 2g
ΔT = 55 - 35 = 20C
Heat = mcΔT = 2 * 200 * 20 = 8000J = 8kJ
The amount of heat required is 8000 J.
What is heat?
Heat is a form of energy that is due to temperature.
To calculate the amount of heat required, we use the formula below.
Formula:
- Q = cm(t₂-t₁).......equatiuon 1
Where:
- Q = Amount of heat required
- m = Mass of the substance X
- c = Specific heat capacity of the substance X
- t₂ = Final Temperature
- t₁ = Initial temperature.
From the question,
Given:
- c = 200 J/g°C
- m = 2.0 g
- t₂ = 55 °C
- t₁ = 35 °C
Substitute these values into equation 1
- Q = 200×2×(55-35)
- Q = 200×2×20
- Q = 8000 J
Hence, the amount of heat required is 8000 J.
