The formula to calculate the energy required to change the temperature of a substance is:
Q = m * c * ΔT
Where:
Q = energy in Joules
m = mass of the substance in grams
c = specific heat capacity of the substance (4.18 J/g°C for water)
ΔT = change in temperature in °C
Plugging in the given values:
Q = 150.0 g * 4.18 J/g°C * (45.0°C - 10.0°C)
Q = 150.0 g * 4.18 J/g°C * 35.0°C
Q = 6270 J
Therefore, the energy required to change 150.0 g of water from 10.0°C to 45.0°C is 6270 J, which is closest to the given option of 6270 J.
How much energy is required to change 150.0 g of water from 10.0°C to 45.0°C? (Cwater = 4.18 J/g • °C)
