Question

Given an example to illustrate why you cannot accurately judge the temperature of an object by how hot or cold it feels to the touch?

Short answer

The body skin has no standard reference temperature.

Step-by-step solution

Given information

One cannot accurately measure the temperature of an object by touching it.

Step 2. Description

When two objects are at the same temperature, they are said to be in thermal equilibrium. The rate at which the thermal equilibrium attained is determined by rate of heat flow from hotter to colder object.

Consider the following example:

A glass of water at room temperature will not seem that hot or cold when we are in the same room. But if we go outside taking that glass to the outside cold weather then for a while the same glass of water feels hotter. It is because our skin temperature changes depending on the surrounding temperature. Hence we cannot judge accurately the temperature of any object by touching it. Our skin has no standard temperature to compare & decide the other object's temperature.

Final answer

One cannot accurately measure the temperature od an object by simply touching it as there is no standard reference temperature of the body skin
