A gold nugget (mass = 376 g) is originally at 398 K is placed in cold water. Its temperature drops to 297 K. If the specific heat capacity of gold is 0.128 J/g°C, how much heat was lost by the gold nugget?

If you burn 10 kilograms of wood in a fire (combustion) what is the weight of the products after the fire has finished burning the wood?

At 300 mm hg, a gas has a volume of 380 l, what is the volume at standard pressure

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
