How many joules of energy are necessary to heat the ice to 0 c?

Answer 1

To calculate the energy needed to heat ice to 0°C, you can use the formula ( Q = mc\Delta T ), where ( m ) is the mass of the ice, ( c ) is the specific heat capacity of ice (approximately 2.09 J/g°C), and ( \Delta T ) is the temperature change (from the initial temperature to 0°C). For example, if you have 100 grams of ice at -10°C, the energy required would be ( Q = 100 , \text{g} \times 2.09 , \text{J/g°C} \times 10 , \text{°C} = 2090 , \text{J} ). Adjust the mass and initial temperature as needed for your specific scenario.
