If a solid changes right to a gas, it's called sublimation. If a gas changes directly to a solid, it's called deposition.
The piece of unknown metal is in thermal equilibrium with water such that Q of metal is equal to Q of the water. We write this equality as follows:
-Qm = Qw
Mass of metal (Cm)(ΔT) = Mass of water (Cw) (ΔT)
where C is the specific heat capacities of the materials.
We calculate as follows:
-(Mass of metal (Cm)(ΔT)) = Mass of water (Cw) (ΔT)
-68.6 (Cm)(52.1 - 100) = 42 (4.184) (52.1 - 20)
Cm = 1.717 -----> OPTION C<span>

Answer:
0.00916432 km/s
21648 inches/minute
Explanation:
1 kilometre / second =
2236.936 miles per hour
20.5/2236.9=0.00916432km/s
1 mile per hour =
1056 inches / minute
20.5×1056=21648 inches/minute
Answer:
Boyles law
Explanation:
I think that is combined gas law.
Answer:
Carbon is found in the hydrosphere dissolved in ocean water and lakes. Carbon is used by many organisms to produce shells. Marine plants use cabon for photosynthesis. The organic matter that is produced becomes food in the aquatic ecosystem.
