Answer:
237.5 K.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 5.2 atm).
V is the volume of the gas in L (V = 15.0 L).
n is the no. of moles of the gas in mol (n = 4.0 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = ??? K).
∴ T = PV/nR = (5.2 atm)(15.0 L)/(4.0 mol)(0.0821 L.atm/mol.K) = 237.5 K.
Answer:
Most indoor growers will want to aim for 50-70% relative humidity, although 60-80% is usually tolerable.
Explanation:
The answer is B: friction.
A definition of friction is a resistance of an object against another, for example a tire against mud, the tire would add friction against the mud to pull away from it.
I don’t need brainliest but please just mark thanks to this answer that would help me a lot, have a nice day :)
Answer:
t = 50 s
Explanation:
P = W/t
Solving for t,
t = W/P = (3430000 J)/(68600 Watts)
= 50 s
Note: 1 Watt = 1 J/s
