A 51 kg block of metal has specific heat of 222 j/kg c. how heat energy must be applied to the block of metal to raise its temperature from 10 c to 22 c?
C stands for degrees Celsius
To calculate the heat energy required to raise the temperature of the metal block, you need to use the formula:
Q = m * c * ΔT
Where:
Q = Heat energy (in Joules)
m = Mass of the metal block (in kilograms)
c = Specific heat capacity of the metal (in J/kg·°C)
ΔT = Change in temperature (in °C)
Given values:
m = 51 kg (mass of the metal block)
c = 222 J/kg·°C (specific heat capacity of the metal)
ΔT = 22 °C - 10 °C = 12 °C (change in temperature)
Now, substitute these values into the formula:
Q = 51 kg * 222 J/kg·°C * 12 °C
Calculate the result:
Q = 134,904 J (Joules)
Therefore, the heat energy required to raise the temperature of the metal block from 10°C to 22°C is 134,904 Joules.
