If 2,035 cal of heat is added to a 500.0 g sample of water at 35.0°C, what is the final
temperature of the water?

39.1 °C

Explanation:

Recall the equation for specific heat:

Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.

You should know that the specific heat of water is 1 cal/g/C.

Using the information in the question:

The final temperature is about 39.1 °C.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
