Answer : The pressure after the temperature change is, 0.752 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
![P\propto T](https://tex.z-dn.net/?f=P%5Cpropto%20T)
or,
![\frac{P_1}{T_1}=\frac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2%7D)
where,
= initial pressure = 0.82 atm
= final pressure = ?
= initial temperature = ![21^oC=273+21=294K](https://tex.z-dn.net/?f=21%5EoC%3D273%2B21%3D294K)
= final temperature = ![-3.5^oC=273+(-3.5)=269.5K](https://tex.z-dn.net/?f=-3.5%5EoC%3D273%2B%28-3.5%29%3D269.5K)
Now put all the given values in the above equation, we get:
![\frac{0.82atm}{294K}=\frac{P_2}{269.5K}](https://tex.z-dn.net/?f=%5Cfrac%7B0.82atm%7D%7B294K%7D%3D%5Cfrac%7BP_2%7D%7B269.5K%7D)
![P_2=0.752atm](https://tex.z-dn.net/?f=P_2%3D0.752atm)
Thus, the pressure after the temperature change is, 0.752 atm
Answer:
Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP. When excess ATP and glucose are present, the liver converts them into a molecule called glycogen, which is stored for later use.
Answer:
Static Electricity
Explanation:
Most likely, in the room, Jim was building up static electricity by friction with the floor, which he released upon contact with a metal object.
