482VP I think is the correct answer.
The two factors that are mainly responsible for determining the thermal energy of a substance are Temperature and Mass.
<h3><u>Explanation:
</u></h3>
Thermal energy is the total energy of the substance.
Temperature: The temperature and thermal energy of a substance are directly related to each other(direct proportion) which means that the greater the temperature, the greater will be the thermal energy of that particular substance.
Mass: Consider a situation, if we have two or more substances that have the same temperature the substance with the highest mass will have the most thermal energy than the others.
Answer:
P = 34.1 L
Explanation:
Given data:
Number of moles = 10 mol
Volume occupy = 15 L
Temperature = 350°C
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
350+273 = 623 K
by putting values,
P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K
P = 511.48atm.L/15L
P = 34.1 L
Answer:
The pressure of the gas inside the plastic bag is 1.971 atm
Explanation:
Since temperature did not change, it means it is constant. This will then be Boyle's law. Thus
P1V1 =P2V2
Where P1 is the initial pressure = 10.2 ATM, P2 is the final pressure which is to be calculated.
V1 is the initial volume = 800.0 mL and V2 is the final volume of the gas = 4.14 L
From the formula,
P2 = P1V1/V2
= 10.2×800÷4.14
= 1.971 atm
The Intermolecular forces increase with increasing polarization of bonds. The strength of Intermolecular forces (and therefore impact on boiling points) is ionic > hydrogen bonding > dipole dipole > dispersion. Boiling point increases with molecular weight, and with surface area.
