Calculate the amount of heat required to raise the temperature of 1kg of water from 30 degrees celsius to 60 degrees Celsius
Q = mc change temp. You'll need the specific heat of water.
125.4kJ
To calculate the amount of heat required to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q = Amount of heat required (in Joules)
m = Mass of the substance (in kilograms)
c = Specific heat capacity of the substance (in Joules per kilogram per degree Celsius)
ΔT = Change in temperature (in degrees Celsius)
In this case, you are trying to find the amount of heat required to raise the temperature of 1kg of water from 30°C to 60°C.
The specific heat capacity of water is approximately 4186 J/kg°C.
Now let's substitute the values into the formula:
Q = 1kg * 4186 J/kg°C * (60°C - 30°C)
Simplifying:
Q = 1 * 4186 * 30
Q = 125,580 Joules
So, the amount of heat required to raise the temperature of 1kg of water from 30°C to 60°C is 125,580 Joules.
