If it takes 7,529 calories of heat to warm 750.0 grams of water, what was the temperature change? The specific heat of water in calories is 1.00 cal/(g•°C).

The temperature change was 10.04 °C.

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system. In this way, there is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case you know:

Replacing:

7,529 cal= 1   *750 g* ΔT

Solving you get:

ΔT=

ΔT= 10.04 °C

So, the temperature change was 10.04 °C.

your parents i think this could be it

what is the question here. i think you messed up.
