<span>pv=nrt; Pressure and moles are constant.
p=nr(150k)/.5 L; Pressure initially
After temp change
pv=nrt; What is volume?
v=nr(350k)/p; p is constant so we can substitute from above
v=nr(350k)/(nr(150k)/.5 L))
v=350/150/.5 L
v=4.66 liters</span>
Im unsure :( maybe try looking up a calorie calculator
Answer:
Four seasons occur on Earth
Explanation:
When the Earth has completely one revolution around the Sun, then it has completed 1 year, and four seasons have occurred in the meantime.
Density = mass / volume
Density = 7.5 g / 5.0 cm3
Density = 1.5 g/cm3
