Question

The maximum temperature the human skin can tolerate without getting blister is
A) $\;40^\circ C$
B) $6^\circ C$
C) $80^\circ C$
D) $100^\circ C$

Answer 1

Blisters are formed when the skin has been damaged either by friction, heat, cold, or even due to chemical exposure.

Complete answer: A burn blister is basically a covering of skin that gets formed over a burnt area of the body in order to protect it from any kind of infection. In case a blister bursts the burned area should be cleaned carefully with lukewarm water and medicinal mild soap. The burnt areas must be protected from the sun, as burnt skin is extremely sensitive to direct sunlight. Application of a good sunscreen with an SPF of 30 or more can further help in preventing scarring. Burns can be categorized depending on the severity of the condition as:
First-degree burn: This affects the epidermal layer of the skin and is considered to be minor. These do not often cause burn blisters.
Second-degree burns: These are slightly deeper than first degree burns, and reach the second layer of skin, known as the dermis.
Third-degree burns: These are very severe, as they can damage both the epidermis and dermis of the skin and are capable of damaging hair follicles, as well as the sweat glands that are located under the skin.
Higher-level burns: These are extremely severe and require immediate attention. These burns reach deep into the skin and damage the muscles, tendons, joints, and even bones in some cases.
So, the correct answer is option C. $80^\circ C$

Note: A blister may be formed even underdressing; while it may be visually unsightly to treat them but it is best to take a hands-off approach to deal with burn blisters.
