To calculate the heat added to 400.0g of concrete when the temperature increases by 0.64 °C, you can use the equation q = mcΔT, where:
q = heat added
m = mass of the concrete (400.0g)
c = specific heat capacity of concrete (0.880 J/g °C)
ΔT = change in temperature (0.64 °C)
1. Substitute the given values into the equation:
q = (400.0g) x (0.880 J/g °C) x (0.64 °C)
2. Calculate the heat added using the values:
q = 224.0 J
Therefore, the heat added to 400.0g of concrete when the temperature increases by 0.64 °C is 224.0 Joules.
