Answer: (a) The magnitude of its temperature change in degrees Celsius is .
(b) The magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .
Explanation:
(a) Expression for change in temperature is as follows.
= 15.1 K
=
=
=
Therefore, the magnitude of its temperature change in degrees Celsius is .
(b) Change in temperature from Celsius to Fahrenheit is as follows.
F = 1.8C + 32
C =
Since, K = C + 273
or,
= 1.8 (15.1)
=
or, =
Thus, we can conclude that the magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .
Answer:
The energy level is 5.
Explanation:
Given that,
n = 3
l = 2
We know that,
l shows the number of sub-shells and define the number of angular nodes.
n shows the number of electron shell.
is a quantum number. It is define the number of energy level in a sub-shells .
is define the spin of the electron.
So, The quantum number is
is
and
for every energy level.
The energy level is 5.
Hence, The energy level is 5.
