Answer:
The temperature of the balloon is 46.34 K.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
Replacing:
0.76 atm* 10 L= 2 moles* 0.082 *T
Solving:
T= 46.34 K
<u><em>The temperature of the balloon is 46.34 K.</em></u>
Answer:
The volume of the gas at given temperature is
Explanation:
= initial pressure of gas = 1 atm
= initial temperature of gas =
= initial volume of gas =
( , 1 mL = 0.001 L)
..[1]
= final pressure of gas = 2.1 atm
= final temperature of gas =
= final volume of gas = ?
..[2]
By dividing [1] and [2] we get combined gas equation :,
Now put all the given values in the above equation, we get:
The volume of the gas at given temperature is
