A helicopter manufacturer heat-treats rotor blades to increase their strength. Heat-treating involves heating a metal up to a high temperature and then quenching, or cooling, it down
quickly. This is typically done by plunging the metal into water.
A chemical engineer wants to quench a 292 g aluminum rotor blade that is originally at 300°C.
She puts the rotor blade in a tub of water, which is originally at 22°C. While the aluminum blade
is still in the water, the water's temperature finalizes to 50°C.
Additional (necessary!) info: The specific heat capacity of water is 4.18 J/(g°C). The specific heat
capacity of aluminum is 0.900 J/(g°C).
Question: What mass of water (in g) does the chemical engineer need to use? Answer this
question in Claim-Evidence-Reasoning format.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
