Question

It takes 2.61 J of heat to raise the temperature of Object A by 1 °C, and 4.40 J to raise the temperature of Object B by 1 °C. Suppose A and B are brought into contact. A is initially hotter. A is seen to cool down by 7.4 °C. How would you calculate the rise in temperature of B? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. change in temperature of B =

Step 1

$$Q_A = -Q_B$$ The heat lost or gained by an object is given by: $$Q = mc\Delta T$$ where m is the mass, c is the specific heat capacity, and $\Delta T$ is the change in temperature. In this case, we are given the amount of heat required to raise the temperature Show more…
