CHEMESTRY HOMEWORK HELP 1. For a certain ideal gas, the temperature is
increased from 200 K to 687 K allowing pressure, which is initially 1 atm, to vary while
the volume and number of moles of gas are
held constant. What is the new pressure?
Answer in units of atm.
2. A gas has a pressure of 1.75 atm and occupies
a volume of 6.3 L. If the gas is compressed to
a volume of 2.13 L, what will its pressure be,
assuming constant temperature?
Answer in units of atm.
3. A sample of argon gas occupies a volume of
253 mL at 18 ◦C. What volume will the
gas occupy at 63.8548 ◦C, assuming constant
pressure?
Answer in units of mL.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
