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)

Confidence Coefficient

The probability that a confidence interval will contain the true parameter value.

Population Proportion

The portion of members in a population that exhibit a specific characteristic, typically expressed as a fraction or percentage.

Population Variance

A measure of the dispersion of a set of data points in a population, indicating how much the members of the population differ from the mean value.

Confidence Interval

A range of values, derived from sample data, that is likely to contain the value of an unknown population parameter, expressed with a certain level of confidence.
