What heat is needed to raise the temperature of 1 kg of water from 14.5 degrees Celsius to 15.5 degrees Celsius?
4180 joule heat is necessary to raise 1 kg of water from 14.5 °C to 15.5 °C.
How much heat in joules is required to raise the temperature of 34.0 kg of water from 15 C to 95 C?
So, that's 4,186 joules per kilogram Celsius degree for water specific heat capacity times its mass of 34 kilograms times the final temperature of 95 degrees Celsius minus the initial temperature of 15. And that gives about 1.1 times 10 to the 7 joules required to raise this temperature that much.
What is the formula for calculating temperature?
Here are the temperature conversion formulas:
- Celsius to Kelvin: K = C + 273.15.
- Kelvin to Celcius: C = K – 273.15.
- Fahrenheit to Celcius: C = (F-32) (5/9)
- Celsius to Fahrenheit: F = C(9/5) + 32.
- Fahrenheit to Kelvin: K = (F-32) (5/9) + 273.15.
- Kelvin to Fahrenheit: F = (K-273.15) (9/5) + 32.
How do you calculate the heat of water?
The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.
