Object A, with Heat Capacity C_A and Initially at Temperature

question 82

Multiple Choice

Object A, with heat capacity C_A and initially at temperature T_A, is placed in thermal contact with object B, with heat capacity C_B and initially at temperature T_B.The combination is thermally isolated.If the heat capacities are independent of the temperature and no phase changes occur, the final temperature of both objects is:

• A)(C_AT_A - C_BT_B)/(C_A + C_B)
• B)(C_AT_A + C_BT_B)/(C_A + C_B)
• C)(C_AT_A - C_BT_B)/(C_A - C_B)

Definitions:

Test Statistic

A standardized value calculated from sample data during a hypothesis test that is used to make a decision about the null hypothesis.

P-value

The probability of obtaining test results at least as extreme as the ones observed during the test, assuming the null hypothesis is true.

Test Statistic

This is a value, derived from sample data, used in hypothesis testing to determine whether to reject the null hypothesis.

Null Hypothesis

The theory suggesting that any noted discrepancies between certain groups are merely the result of sampling or experimental inaccuracies, asserting no substantial variance exists.
