How is thermal energy apart of weather changing
kirza4 [7]

Answer:

Heat, in the form of thermal energy, naturally moves from warmer substances to colder ones. When the ocean is warmer than the atmosphere, it transfers heat — through conduction and radiation — to make the air warmer. ... This redistributes thermal energy and causes changes in the weather.

A gas has a volume of 27.5 L at 302 K and 1.40 atm. How many moles are in the sample of gas?
ioda

Answer:

1.55 mol  

Step-by-step explanation:

We can use the <em>Ideal Gas Law</em> to solve this problem.

pV = nRT     Divide both sides by RT

 n = (pV)/(RT)

Data:

p = 1.40 atm

V = 27.5 L

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 302 K

Calculations:

n = (1.40 × 27.5)/(0.082 06 × 302)

  = 1.55 mol
