Answer:

Solid KOH will corrode the skin but a solution of KOH in triethyleneglycol will not.

The temperature is monitored with an external thermometer also because the sand looses some heat to energy exchange with the surrounding.

Explanation:

KOH is a deliquescent solid which is very corrosive upon contact with skin. Its solution in an organic liquid is not corrosive.

Secondly, when exposed to the surrounding, heat is lost according to the laws of thermodynamics.

It is given that the price of the carpet is $ 28.99 per square yard

Step 1: Convert square yard to square meter

1 square yard = 0.836 square meter

Step 2: Calculate the cost/square meter

Now based on the relation in step (1) we can write

0.836 square meter of carpet costs $ 28.99

Therefore the cost of 1 square meter of the carpet would be

= $ 28.99 * 1 sq meter/0.836 sq meter

= $ 34.68
