How much heat is required to raise the temperature of a 65-g sample of water from 32 degrees celsius to 65 degrees celsius
q = heat required = mass H2O x specific heat H2O x (Tfinal-Tinitial)
To calculate the amount of heat required to raise the temperature of a substance, you need to use the equation:
q = mcΔT
Where:
q is the amount of heat energy (in joules)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in J/g°C)
ΔT is the change in temperature (in °C)
For water, the specific heat capacity is approximately 4.18 J/g°C.
Given:
m = 65 grams
ΔT = (65°C - 32°C) = 33°C
c = 4.18 J/g°C
Let's substitute these values into the equation:
q = (65 g)(4.18 J/g°C)(33°C)
Now we can calculate the amount of heat energy (q):
q = 8763.9 J
So the amount of heat required to raise the temperature of the 65-g sample of water from 32 degrees Celsius to 65 degrees Celsius is approximately 8763.9 Joules.
