Calories of heat absorbed by water = (Mass undergoing change)(Change in temp.)How much heat is needed to warm 125 g. of water from 25 degrees Celsius to 100 degrees Celsius. Thank you very much!
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
If you want q in calories, specific heat H2O = 1 cal/g*C
To determine the amount of heat needed to warm water from one temperature to another, you can use the equation Q = (m)(ΔT), where Q represents the amount of heat, m represents the mass of the substance undergoing the temperature change, and ΔT represents the change in temperature.
In this case, you are given the mass of water (m = 125 g) and the initial and final temperatures (25°C and 100°C, respectively). The next step is to calculate the change in temperature:
ΔT = Final temperature - Initial temperature
ΔT = 100°C - 25°C
ΔT = 75°C
Now, using the equation Q = (m)(ΔT), we can substitute the values:
Q = (125 g)(75°C)
Q = 9375 calories
Therefore, you would need 9375 calories of heat to warm 125 g of water from 25 degrees Celsius to 100 degrees Celsius.
