Calculate the amount of heat (calories) needed to raise the temp of 10.0g of water from 10.0 c to 75.0 c ??
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
7500
20
To calculate the amount of heat needed to raise the temperature of water, we can use the specific heat capacity of water, which is 1 calorie per gram per degree Celsius. The formula to calculate heat is:
Q = m * c * ΔT
Where:
Q = Amount of heat (in calories)
m = Mass of the substance (in grams)
c = Specific heat capacity (in cal/g°C)
ΔT = Change in temperature (in °C)
Given:
m = 10.0 g (mass of water)
c = 1 cal/g°C (specific heat capacity of water)
ΔT = 75.0°C - 10.0°C = 65.0°C (change in temperature)
Let's substitute these values into the formula:
Q = 10.0 g * 1 cal/g°C * 65.0°C
Q = 650.0 calories
Therefore, the amount of heat needed to raise the temperature of 10.0g of water from 10.0°C to 75.0°C is 650.0 calories.
