A 143-g sample of mercury is at an initial temperature of 25 °C. If 1067 joules of heat are applied to the sample, what is the final temperature of the mercury? The specific heat capacity of mercury is 0.14 J/(g∙ °C).
7. Frost forms on a grapefruit when the temperature of its surface reaches 0°c At night, the grapefruit is assumed to be completely surrounded by the night sky acting as a black body at -45°C. The emissivity of the grapefruit is approximately 0.93 while the heat transfer coefficient between the grapefruit and the air surrounding it is 17 W/m°C. The grapefruit may be assumed to be at steady state without internal heat generation and energy conduction up the stem may...
