5 0

Answer:

Thermal energy is the answer of burning wood

Explanation:

Thermal energy, internal energy present in a system in a state of thermodynamic equilibrium by virtue of its temperature. Thermal energy cannot be converted to useful work as easily as the energy of systems that are not in states of thermodynamic equilibrium.

4. A gas occupies 1.56 L at 2.00 atm. What will be the volume of this gas if the pressure becomes 4.00 atm?
tekilochka [14]

Answer:

<u>0.78 L</u>

Explanation:

From Boyle's Law :

P₁V₁ = P₂V₂

Here :

  • P₁ = 2.00 atm
  • V₁ = 1.56 L
  • P₂ = 4.00 L

Solving :

  • V₂ = P₁V₁ / P₂
  • V₂ = 2 x 1.56 / 4
  • V₂ = 1.56 / 2
  • V₂ = <u>0.78 L</u>

How many moles of gas would you have if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature
seraphim [82]

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Explanation:

Given: Volume = 38.0 L

Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm

Temperature = 273.15 K

Using ideal gas equation, the moles of gas will be calculated as follows.

PV = nRT\\

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T =temperature

Substitute the values into above formula as follows.

PV = nRT\\1.9 atm \times 38.0 L = n \times 0.0821 L atm/mol K \times 273.15 K\\n = \frac{1.9 atm \times 38.0 L}{0.0821 L atm/mol K \times 273.15 K}\\= 3.2 mol

Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.
