A pond of water at 0°C is covered with a layer of ice 4.00 cm thick. If the air temperature stays constant at -10.0°C, what time interval is required for the ice thickness to increase to 8.00 cm? Suggestion: Use Equation 19.18 in the form ΔΤ kA- dt and note that the incremental energy dQ extracted from the water through the thickness x of ice is the amount required to freeze a thickness dx of ice. That is, dQ= L,pA dx, where p is the density of the ice, A is the area, and L,is the latent heat of fusion.

A canister with a piston contains 1.05 kg of air at 30.0°C and 1.25 x 105 Pa. Energy is transferred by heat into the system as it expands and the pressure rises to 4.25 x 105 Pa. Throughout the expansion, the relationship between pressure and volume is given by P = cv1/2) where C is a constant. Air may be modeled as a diatomic ideal gas with a molar mass of M = 28.9 g/mol. Determine the following. (a) initial volume (in m3) 0.01477 The ideal gas law may be used to describe the air in any state, Since we want the initial volume, we should use the pressure and temperature for the initial state.

A thirsty nurse cools a 2.40 L bottle of a soft drink (mostly water) by pouring it into a large aluminum mug of mass 0.249 kg and adding 0.122 kg of ice initially at -14.3 ∘C. If the soft drink and mug are initially at 21.0 ∘C, what is the final temperature of the system, assuming no heat losses? Express your answer in degrees Celsius.
Indirect Cooling With Liquid Nitrogen. You are designing a system to cool an insulated silver plate of dimensions 2.00 cm x 2.00 cm x 0.60 cm. One end of a thermally insulated copper wire (diameter D = 2.60 mm and length L = 14.0 cm) is dipped into a vat of liquid nitrogen (T= 77.2 K), and the other end is attached to the bottom of the silver plate. (a) If the silver plate starts at room temperature (70.0 °F), what is the initial rate of heat flow between the plate and the liquid nitrogen reservoir?

An object of mass 7.90 kg falls through a height of 40.0 m and, by means of a mechanical linkage, rotates a paddle wheel that stirs 0.620 kg of water. Assume that the initial gravitational potential energy of the object is fully transferred to thermal energy of the water, which is initially at 13.0°C. What is the temperature rise of the water?
A typical nuclear reactor generates 1000 MW of electric energy. In doing so, it produces “waste heat” at a rate of 2000 MW, and this heat must be removed from the reactor. Many reactors are sited next to large bodies of water so that they can use the water for cooling. Consider a reactor where the intakewater is at 18°C. State regulations limit the temperature of the output water to 30°C so as not to harm aquatic organisms. How many kilograms of cooling water have to be pumped through the reactor each minute?
