A resistance thermometer reads 16.5 Ω in pure melting ice and 42.5 Ω in steam at standard atmospheric pressure. What will be its resistance at room temperature of 30.0oC?

A solid sphere of volume 0.5 m³ is completely submerged in water. What is the buoyant force acting on the sphere? (Density of water = 1000 kg/m³, g = 9.8 m/s²)

__________ absorbs all radiant energy that falls on it.

The gauge pressure in a car tire is 305 kPa when its temperature is 15 degrees C. After running at high speed, the tire has heated up and its pressure is 3б0 kPa. What is then the temperature of the gas in the tire? Assume atmospheric pressure to be 101 kPa.

250 g of water at 20.0 degrees C is poured into a 500-g aluminium pan off the stove with a temperature of 150degrees C. The pan is placed on an insulated pad, and heat transfer to the air is neglected in the short time needed to reach equilibrium. Assume that a negligible amount of water boils off. What is the temperature when the water and pan reach thermal equilibrium?

In a demonstration experiment to estimate the size of a molecule, an oil droplet of mass 0.9 mg and density 918 kg/m³ spreads out into a circle of radius 41.8 cm on water surface. Calculate the diameter of the oil molecule.

A molecule of a gas whose mass is 4.65×10-26 kg has a root-mean-square speed for that gas at 0.0 degrees C at the surface of the earth. Suppose the molecule goes up without colliding with other molecules, how high up would it rise? [Take kB=1.38×10-23 J/K; g=9.8 ms-1]

A partition between two thermodynamic systems through which heat can pass from one system to another is said to be____________________________

Measurement of heat is referred to as ____________

A bullet of mass 3.0 g moving at a speed of 180 ms-1 strikes and is embedded in a sandbag. Calculate the change in temperature of the bullet if all of its kinetic energy is converted to heat energy in the sandbag. [For the bullet, take c = 128 J/kg. degrees C].
