In physics, the Ideal Gas Law describes the relationship among the pressure, volume, and temperature of a gas sample. The law is represented with the formula PV = nRT, where P is the pressure, V is the volume, T is the temperature, n is the amount of gas, and R is a physical constant. Select all the equations that are equivalent to the formula PV = nRT. Group of answer choices
A. P = VnRT
B. R = PVnT
C. V = nRT / P
D. n = PV / RT
E. T = nR / PV

The temperature in degrees Kelvin is 273 degrees less than the temperature in degrees Celsius. Use the formula C = 5/9(F - 32) to write a formula for the temperature in degrees Fahrenheit F in terms of the temperature in degrees Kelvin K. A. F = 9/5(K - 273) - 32
B. F = 5/9(K + 273) + 32
C. F = 9/5C + 32

Ответ:
1. D and C
2. F = 9/5(k-273) + 32
Step-by-step explanation:
1. We simply want to write the given equation in different forms;
PV = nRT
So P = nRT/V
R = PV/nT
V = nRT/P
n = PV/RT
T = PV/nR
So the correct expressions are;
D, C,
2. we want to make F the subject of the formula, that would be;
C = 5/9(F - 32)
9C = 5(F - 32)
divide both sides by 5
9C/5 = F - 32
F = 9C/5 + 32
But K = C + 273
So C = K - 273
Insert this into the equation, we have
F = 9(K-273)/5 + 32
