When the volume of a gas is
Fudgin [204]

Answer: The initial volume is 593.76mL

Step-by-step explanation:

As you do not say anithing about the pressure, i guess that the pressure remains constant.

If the gas is an ideal gas, we have:

P*V = n*R*T

where P is pressure, n is number of moles and R is a constant.

Now, initially we have:

P*Vi = n*R*315°C

finally we have:

P*825mL = n*R*452°C

Now we can take the quiotient of those two equations and get:

(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)

Now we have:

Vi/852mL = 315/452

Vi =  (315/452)*852mL = 593.76mL

So when we expand the gas at constant pressure, we increase the temperature.

The equation 5m=36.25 models a constant rate situation. What is the value of 7m
Bond [772]

Answer:

7m = 50.75

Step-by-step explanation:

5m=36.25

We can solve this for m by dividing each side by 5

5/5m=36.25/5

m = 7.25

We want to find 7m

7(7.25) = 50.75
