Answer : The new pressure if the sample placed in a 2.00-L container is, 0.494 atm.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 0.988 atm
= final pressure = ?
= initial volume = 1.00 L
= final volume = 2.00 L
Now put all the given values in the above equation, we get:
Thus, the new pressure if the sample placed in a 2.00-L container is, 0.494 atm.
<u>Answer:</u> The final temperature of the sample is 62.66°C
<u>Explanation:</u>
To calculate the amount of heat absorbed, we use the equation:
where,
Q = heat absorbed = 16.7 kJ = 16700 J (Conversion factor: 1 kJ = 1000 J)
m = Mass of the sample = 225 g
c = specific heat capacity of sample =
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of the sample is 62.66°C
