A 35-g block of ice at -14°C is dropped into a calorimeter (of negligible heat capacity) containing 400 g of water at 0°C

When the system reaches equilibrium, how much ice is left in the calorimeter? The specific heat of ice is 2090 J/kg ? K, that of water is 4186 J/kg ? K, and the latent heat of fusion of water is 33.5 × 104 J/kg. A) 32 g
B) 33 g
C) 35 g
D) 38 g
E) 41 g

Why is Saturn almost as big as Jupiter, despite its smaller mass?

A) Jupiter's greater mass compresses it more, thus increasing its density. B) Saturn's rings make the planet look bigger. C) Saturn is further from the Sun, thus cooler, and therefore less compact. D) Saturn has a larger proportion of hydrogen and helium than Jupiter, and is therefore less dense. E) Jupiter's strong magnetic field constrains its size.

The atom 40K decays radioactively to the gas 40Ar. An ancient rock is found to contain enough 40Ar gas to indicate that 77.0% of the 40K in the rock has decayed to 40Ar since the rock solidified

(Any previous argon would have boiled out of liquid rock.) How long ago did the rock solidify? The half-life of 40K is 1.25 billion years. A) 2.65 billion years B) 0.471 billion years C) 1.80 billion years D) 0.324 billion years
