Answer:
B. Able to be lost or gained in chemical reactions.
How about P-La-S-Ti-C W-Ra-P?
Answer:
The pressure of the gas increased (if temperature remained constant).
The Boyle's law supports this observation.
Explanation:
The initial measurements of the gas are given as;
volume = 100 L
Pressure = 300 kpa
The second measurement is given as;
Volume = 75 L
The second reading implies that the volume of the gas has decreased. If the temperature of the gas remained constant, then the pressure must have increased according to the Boyle's law;
At constant temperature, the pressure of a given mass of an ideal gas is inversely proportional to its volume.
Answer:
1.42m/s
Explanation:
velocity=displacement/time
v=50/35=1.42m/s
