A block of aluminum (C = 0.9 J/gºC) has been sitting in boiling water with a temperature of 99°C for 5 minutes. This hot block of aluminum is dropped into 280 grams of cool water (C =
4.18 J/g°C) that had a temperature of 16°C before the metal block was added. Afterwards,
the aluminum block and the water both have a temperature of 29°C. What is the mass of
the aluminum block?

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
