the answer is pressure and temperature.
the law states that for an ideal gas, the pressure of a gas is directly proportional to the absolute temperature, at constant volume.
- it can be expressed as: (pi/ ti)v = (pf /t f)v
where, pi and ti are the initial pressure and temperature, pf and t f are the final pressure and temperature
- the letter (v) is written out of the brackets means that the volume is constant..
the answer is by adding the vectors.

the river current is moving with velocity vc=10 km/h in a certain direction relative to the shore. the boat is moving with velocity vb=10 km/h relative to the current, and in the same direction as the current, so the total velocity of the boat relative to the shore will be equal to the sum of the two vectors (because they are in the same direction):
v=vb+vc = 10 km/h + 10 km/h = 20 km/h
