Alculate the amount of heat transferred when 710 grams of water warms from an initial temperature of 4.0 ºC to a final temperature of 25.0 ºC. The specific heat capacity of liquid water is 4.184 J/g ºC. Please express you answer as a number in units of kJ, and be careful about the sign (is the answer a positive or negative number?) since that shows the direction of heat flow.

The Quantity of heat require is

Step-by-step explanation:

This problem bothers on the topic of heat capacity.

Given data

mass of water m=  

converting from grams to kg we have =

initial temperature T1= 4°C

final temperature T2= 25°C

heat capacity of water =

The expression for the quantity of heat required is given has

substituting our given data we have

In kilograms we have to divide by

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
