The normal boiling point of radon is -95.8 F. What is this temperature in kelvins?

What is the vrms of hydrogen on the surface of the sun if its temperature is 5.36E3 degC? What is the vrms of hydrogen on the surface of the earth if its temperature is 21.2 degC?

A window has heavy curtains in front of it. At night the curtains are closed to minimise heat loss. During the day the curtains are pulled aside exposing the glass window. How much heat is lost through the 1.0 m x 1.0 m square glass window pane that is 4mm thick when the inside temperature is 20 degree C and the outside temperature is -6 C (negative 6.0) in 12 hrs? ( 1m = 100 cm) (1m = 1000mm) %3D

#19.13 FIND THE GIVEN, REQUIRED, SOLUTION AND EXPLAIN PER STEPS

As radioactive plutonium isotopes decay, they generate heat as a byproduct. Pu-239 generates 1.9W/kg of heat. How much heat will 1.25molof Pu-239 release after decaying for three hours? Express this quantity in units of calories. Assume Pu-239 has a molecular weight of 244g/mol.

2 A 200-L tank contains krypton at a pressure of 1335 psi (9312kPa) at 70°F (21.1°C). The gas is labeled with 85Kr to a specific activity of 2 Ci per Kr. The krypton is leaking out of the tank at a rate of 1 mL (at STP) per minute. The tank is in a storage room 3 m x 3 m x 2 m high, and the air in the room is exchanged four timer per hour. What is the steady-state concentration in the room, in uCi/cm3 and Bq/m3?

In intergalactic space, there is an average of about one hydrogen atom per cubic centimeter and the temperature is 3.50 K What is the absolute pressure? Boltzmann constant is 1.38×10-23 J/K Pa

Presents the diagram of the problem, necessary formulas, clearance and numerical solution: A small hole in a furnace acts like a blackbody. Its area is 1 cm2 and its temperature is the same as that inside the oven, 1,727 ◦C. How many calories are radiated out of the hole each second?

Di O 11:PA (1) Suppose a person is covered head to foot by wool clothing with average thickness of 2 cm and is transferring energy of 6000 joules by conduction through the clothing for 2 minutes. What is the temperature difference across the clothing, given the surface area is 1.4m?? (Given: Thermal conductivity of wool is 0.04 W/mK) The difference in temperature = (2) A 9.15 kg sample of water at 11°C is in a calorimeter. You drop a piece of iron with a mass of 0.41 kg at 260°C into it. After the sizzling subsides, what is the final equilibrium temperature? (Given: Sp. Heat of water 1cal/g°C & Sp. Heat of iron is 0.106 cal/g°C) Equilibrium temperature in celcius =

Nuclear scientists have determined that a fourth state of matter exists: plasma. The state of plasma is reached when matter acquires a temperature so high that some of the molecules and atoms are broken down into ions and electrons. Stellar and interstellar matter mostly occur as forms of plasma. On Earth, plasma exists in the ionosphere, in flames, and in chemical and nuclear explosions. Matter in a controlled thermonuclear reactor also exists in a plasma state. Plasma is most like a gas. However, it differs from un-ionized gas in that it is a good conductor of electricity and heat. Scientists hope to understand the occurrence of plasma in nature and to harness it as an inexpensive energy source. 26. Based on the passage, how can the cost of developing thermonuclear power with plasma be defended? A. It is applicable to all technologies. B. A plasma power source can be used without special equipment. C. It can provide an inexpensive power source. bagga bniy D. It is almost perfected…
