Answer:
E= 3.829 x 10-16 J
Explanation:
Data Given
Frequency= 5.78 x 10^17 Hz
Energy in joules = ?
Solution:
Formula used to calculate Energy
E= hv…………….. (1)
Where E is Energy
h is Planks Constant = 6.626 x 10–34 J s
v is frequency
The given frequency is in Hz (Hertz)
Hz is equal to s-1 (per second)
1 hertz = 1 /second
Putting the values in Equation 1
E= (6.626 x 10–34 J s) (5.78 x 1017 s-1)
E= 3.829 x 10-16 J
Answer:
Explanation:
Given that:-
Pressure = 
The expression for the conversion of pressure in Pascal to pressure in atm is shown below:
P (Pa) = 
P (atm)
Given the value of pressure = 43,836 Pa
So,
= 
atm
Pressure = 6.80977 atm
Volume = 
= 2.3 L ( 1 m³ = 1000 L)
n = 2 mol
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
6.80977 atm × 2.3 L = 2 mol × 0.0821 L.atm/K.mol × T
⇒T = 95.39 K
The expression for the kinetic energy is:-
k is Boltzmann's constant = 
T is the temperature
So, 
High temperature and low pressure. At high temperature, the kinetic energy of the gas particles increases and they move farther from each other. At low pressure, the gas particles are less likely to collide with each other.

Explanation:
The properties of matter that do not depend on the size or quantity of matter in any way are referred to as an intensive property of matter. Temperatures, density, color, melting and boiling point, etc., all are intensive property as they will not change with a change in size or quantity of matter.
