How much heat (in joules) is required to raise the temperature of 34.0 kg of water from 15°C to 95°C?
Heat needed to raise water to a specified temperature.
Answer to Problem 2P
Solution:
Heat needed to raise water to a temperature of 95 C is 11385920 J
Explanation of Solution
Given:
is thermal energy to be determined
of water is 4186 J/kgK
is 34 kg
is 95 C
is 15 C
Formula Used:
The formula used is the relation between temperature and specific heat from thermodynamics
Where,
is the heat transferred
is the specific heat
is the mass
is the final temperature
is the initial temperature
Calculation:
Inserting the given values in the heat capacity formula:
J
