Explanation:
acid should be handled with caution because it is dangerous as it may burn the skin
Answer:
632.32 mmHg
Explanation:
Millimetre mercury:
It is the monometric unit of pressure. It is define as "The pressure exerted by the column pf mercury at the height of 1 millimetre.
It is represented as mmHg.
It can also be written as mm Hg.
Atmosphere (atm):
It is barometric pressure, define as "The force exerted by atmospheric column on per unit area".
It is written as "atm".
Conversion of atm to mmHg:
0.832 atm × 760 mmHg / 1 atm
632.32 mmHg
Answer: 1800 L
Explanation:
Given that,
Original pressure of gas (P1) = 180 kPa
Original volume of gas (V1) = 1500 L
New pressure of gas (P2) = 150 kPa
New volume of gas (V2) = ?
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1 = P1V2
180 kPa x 1500 L = 150 kPa x V2
270000 kPa•L = 150 kPa•V2
Divide both sides by 150 kPa
270000 kPa•L/150 kPa = 150 kPa•V2/150 kPa
1800L = V2
Thus, the new volume of the gas is 1800 liters.
<u>Given:</u>
Volume of gas = 215 ml
Initial temperature T1 = 20C = 20 +273 = 293 K
Initial pressure P1 = 1 atm
Final pressure P2 = 1.5 atm
<u>To determine:</u>
The final temperature T2
<u>Explanation:</u>
Based on Gay-Lussac's Law:
P α T
Therefore we have the relation:
P1/T1 = P2/T2
T2 = P2T1/P1 = 1.5 *293/1 = 439.5 K
Converting from Kelvin to degrees C we have:
T2 = 439.5 - 273 = 166.5 C
Ans: The final temperature is 439.5 K or 166.5 C
