Answer:
T₂ = 859.4 K
Explanation:
Given data:
Initial volume of gas = 32.0 L
Initial temperature = 2°C (2 + 273 = 275 k)
Final temperature = ?
Final volume = 1.00 ×10²L
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₂ = V₂T₁ /V₁
T₂ = 1.00 ×10²L × 275 K / 32.0 L
T₂ = 27500 L.K / 32.0 L
T₂ = 859.4 K
Answer:
false
Explanation:
a physical property can be observed and stay the same but a chemical property can't
Answer:
C. 12.8 liters.
Explanation:
The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains 
molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:
(1)
(1b)
Where:
- Pressure, measured in pascals.
- Volume, measured in liters.
- Amount of molecules, no unit.
- Avogadro's number, no unit.
- Ideal gas constant, measured in pascal-liters per mole-Kelvin.
- Temperature, measured in Kelvin.
If we know that 
, 
, 
, 
and 
, then the volume of carbon dioxide at STP is:
Therefore, the correct answer is C.
