Using the same sample of gas (P1 = 175 torr , T1 = 2 ∘C ), we wish to change the pressure to 1750 torr with no accompanying change in volume or amount of gas. What temperature T2, in Celsius, is needed to reach this pressure? Express your answer with the appropriate units.

i think it is true since you can test the answer and can use observations to complete it.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
