An aluminum cup of 100 cm3 capacity is completely filled with glycerine at 22 degrees C. How much glycerine, if any, will spill out of the cup if the temperature of both the cup and the liquid is increased to 28 degrees C?

A PhysCast on experimental uncertainties.

In this PhysCast we want to review Bernouillis equation, understand what the terms mean, and how they can be applied to a series of situations where we have fluid flow through a pipe.

Calculate the minimum amount of energy required in joules to completely melt 130 g of silver which is initially at 15.0 degrees C.

An iron ball is suspended by a thread of negligible mass beneath a floting cylinder. The cylinder has a height of 6.0 cm, a top surface area of 12.0 cm2 and a density of 0.3 g/cm3. If the cylinder is submerged by 2.0 cm what is the radius of the iron ball?

A fully loaded Volvo station wagon has a mass of 1950kg. If each of its four tires is inflated to a gauge pressure of 230kPa, what is the total tire area in contact with the road?

A PhysCast on buoyancy.

This is a numerical error propogation example where we're asked to find the density and uncertainty in density of two objects.

In this question a 50 g ice cube is dropped into 200 g of water in a thermally insulating container. If the water is initially at 25 degrees C and the ice comes from the freezer at -15 degrees C, what is the equilibrium temperature?

In this question we are asked what mass of steam at 100 degrees C must be mixed with 150 g of ice at its melting point in a thermally insulating container to produce water at 50 degrees C?
