The ceramic glaze on a red-orange Fiestaware plate is U2O3 and contains 50.0 grams of 238U , but very little 235U. If energy is worth 12.0 cents per kW.h , what is the monetary value of the energy emitted? (These plates went out of production some 30 years ago, but are still available as collectibles.)
During a bout with the flu an 80-kg person ran a fever of 39 oC. Consider that the specific heat of any human body is 3470 J/kg K, how much energy does the body need to burn to reach the fever temperature?
The answer (in fundamental SI unit) is ___________ (type the numeric value only, dont use scientific notation)
A block of ice (m = 13 kg) at a temperature of T= 0 degrees C is placed out in the sun until it melts, and the temperature of the resulting
water rises to T,= 26 degrees C. Recall that the specific heat of water is c = 4186 J/(kg-K), and its latent heat of fusion is Lf= 3.34 × 10° J/kg.
Input an expression for the amount of energy, Em, needed to melt the ice into water.

This heat transfer causes a rapid increase in temperature if the cooling system fails (1 watt = 1 joule/second or 1 W = 1 J/s and 1 MW = 1 megawatt).

(b) How long would it take to obtain a temperature increase of 2000 C, which could cause some metals holding the radioactive materials to melt? (The initial rate of temperature increase would be greater than that calculated here because the heat transfer is concentrated in a smaller mass. Later, however, the temperature increase would slow down because the 500,000-kg steel containment vessel would also begin to heat up.)arrow_forward

The Sun's core has a temperature, Tcore 1.6 x 107 K. The mass density of the core is approximately p= 1.5 x 10 kg m3. Assuming the core has the same mass fraction of hydrogen as the Sun's atmosphere (XH = 0.75), approximate the number of fusion reactions between two hydrogen nuclei (two free protons) per second. You may assume that the temperature and density are uniform throughout the core (not realistic!), which extends from the center of the sun out to about Ro/5, and that particles within the core act like a non-relativistic ideal gas (Maxwellian velocity distribution) with all reactions happening at the same relative velocity. Also assume the cross-sectional area for a proton-proton reaction is o = 2.75 x 1048 m2. %3Darrow_forward
