Answer : q = 6020 J, w = -6020 J, Δe = 0
Solution : Given,
Molar heat of fusion of ice = 6020 J/mole
Number of moles = 1 mole
Pressure = 1 atm
Molar heat of fusion : It is defined as the amount of energy required to melt 1 mole of a substance at its melting point. There is no temperature change.
The relation between heat and molar heat of fusion is,
(in terms of mass)
or, 
(in terms of moles)
Now we have to calculate the value of q.
When temperature is constant then the system behaves isothermally and Δe is a temperature dependent variable.
So, the value of 
Now we have to calculate the value of w.
Formula used : 
where, q is heat required, w is work done and 
is internal energy.
Now put all the given values in above formula, we get
w = -6020 J
Therefore, q = 6020 J, w = -6020 J, Δe = 0
An increase in H+ concentration will decrease OH- concentration is the
reason why it's impossible.
<h3>What is an Acidic and Basic compound?</h3>
An acidic compound has the presence of H+ ions in them while basic
compounds have the presence of OH- ions.
In a solution , as the number of Hydrogen ions increases, it leds to a
corresponding decrease in the Hydroxide ions which is the reason why
they can't coexist at the same time.

Based on exposure time and place, the Sun's radiation may have harmful or beneficial effects.
<h3>What is solar radiation?</h3>
Solar radiation refers to the radiation from the Sun in the form heat, light and other forms of radiation.
The radiation from the Sun may have harmful or beneficial effects.
The effects of the Sun's radiation can be classified as BE, HE or SP as follows:
- BE- UV rays can help treat some health conditions. It creates Vitamin D
- SP- Use sunblock lotion with SPF 15 during hot days.
- BE- With the presence of sunlight, farmers can dry their crops.
- HE- UV rays can damage the tissue in your eyes.
- BE- Research says that sunlight helps moods.
- HE- Too much exposure from the sun can cause skin cancer.
- SP- Use sunglasses when you stay under the sun.
- SP- Wear a wide- brimmed hat on sunny days.
- BE- Humans can do recreational activities on a sunny day.
- SP- Wear sunglasses that filter UV light.
- HE- Prolonged exposure to the sun’s heat makes your skin age faster than normal.
- HE- Too much heat from the sun can cause heat stroke and loss of water.
- BE- Sunlight helps strengthen your immune system.
- BE- The vitamin D made thanks to the sun plays a big role in bone health.
- SP- Avoid sun in the middle of the day, from about 10 a.m. to 3 p.m.
