Answer:
Striped should be the answer
The car has greater momentum because it has more mass than a bike, even if they have the same speed. I hope this helped! :-)
Answer: (a) Mole fraction of
is 0.66.
Mole fraction of
is 0.33
(b) The partial pressure of
is 1.98 atm.
The partial pressure of
is 0.99 atm.
(c) The total pressure is 3.0 atm
Explanation:
Given: Volume =
(1
= 1 L) = 22.4 L
Moles of
= 2.0 mol
Moles of
= 1.0 mol
Total moles = (2.0 + 1.0) mol = 3.0 mol
Temperature = 273.15 K
- Now, using ideal gas equation the total pressure is calculated as follows.

where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.

- The mole fractions of each component:
The mole fraction of
is calculated as follows.

The mole fraction of
is as follows.

- The partial pressures of each component:
Partial pressure of
are as follows.

Partial pressure of
are as follows.

energy to raise temperature is 590 J
Given:
mass of silver sample = 0.5 kg
initial temperature = 200 k
final temperature = 205 k
specific heat of silver = 236 j/kgk
To Find:
energy to raise temperature
Solution: The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.
Q = cmΔt
where c= constant of proportionality, called specific heat capacity of the body
Q = mass x specific heat x ∆t
= 0.5 x 236 x ( 205-200 )
= 590 J
So, energy to raise temperature is 590 J
