Nuclear fusion, the energy source of the sun and hydrogen bombs, occurs much more readily when the average kinetic energy of the atoms is high — that is, at high temperatures. Suppose you want the atoms in your fusion experiment to have average kinetic energies of 2.10  10-14 J. What temperature is needed? (in K)

A certain sandwich cookie contains 55 CC of nutritional energy. For what amount of time must you swim in order to work off three cookies if swimming consumes 510 C/hC/h AND Instead of swimming you decide to run for 40 min at a pace that works off 860 C/hC/h. How many cookies have you worked off?

In testing a new drug, you heat a 0.5-kilogram sample using a hot plate. Assume no energy is lost in the process (i.e. the process is 100% efficient). The corresponding change in temperature and energy readings observed during the heating process are graphed as shown. Watch your units!!!! 16000 14000 12000 10000 8000 Q= 72 AT 6000 4000 2000 100 150 200 250 Change in Temperature (AT) [deg F] What is the specific heat capacity of the fluid in units of joules per gram kelvin? Hint: compare the trendline equation to the thermal energy equation. * A Energy (Q) [J]

Thermal expansion: The exterior of a supersonic Airplane is made of aluminum which has a coefficient of linear expansion of 24.0 x10^-6 1/K. If the plane is 45.6m long at a temp of 10 C. When the plane is in flight the friction due to air resistance increases the temp of the aluminum to 150 C. What is the change in length of the plane?

Suppose 9.30 x 105 J of energy are transferred to 2.00 kg of ice at 0°C. (a) Calculate the energy required to melt all the ice into liquid water. (b) How much energy remains to raise the temperature of the liquid water? (c)Determine the final temperature of the liquid water in Celsius.

19. The following fission reaction (shown below) occurs in a nuclear power plant. There are 1.50 x 1016 uranium-235 atoms that are simultaneously undergoing this reaction. The uranium is surrounded by 17.5 kg of heavy water, which has a specific heat capacity of 4.70 x 10³ J/kg °C. If 90% of the energy released in the nuclear reactions is absorbed as thermal energy by the heavy water, determine the increase in temperature of he heavy water. ✔✔✔✔ 235U+n→ Zr + 139 Te + 3(n) 92 40 52 mzr-94 = 93.906 u MTe-139 = 138.935 u Mu-235 = 235.044 u

Consider two containers, one holding 1 kg of argon at 300 K and the other holding1 kg of krypton at 500 K. In each vessel, the average microscopic speed is given bȳv = √8kbT /πm

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?
