What happens when you put one hand in ice water and the other in warm water
NikAS [45]

When you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

<h3>What is thermal adaptation?</h3>

The ability of a body to adjust to temperature is called thermal adaptation. Mammals are the animals who can adjust the temperature of their body.

The reptiles are not able to adjust their body temperature, because they are poikilothermic. They have to take the help of outer environment to adjust their body temperature.

Thus, when you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

What is the concept of Dimensional Analysis?
7nadin3 [17]

Answer:

In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometers, or pounds vs. kilograms) and tracking these dimensions as

The molarity of the lake water is 0.00001 M and the pH of lake water is 5.

The lake water is acidic.

Explanation:

Data given:

molarity of base solution Mbase = 0.1 M

volume of the base solution Vbase = 0.1 ml or 0.0001 litre

volume of lake water Vlake = 1000ml  or 1 litre

molarity of the lake water, Mlake = ?

Using the formula for titration:

Mbase X Vbase = Mlake X

Mlake = \frac{Mbase X Vbase }{Vlake}

Putting the values in the equation:

Mlake = \frac{0.0001 X 0.1}{1}

Mlake = 0.00001 M

The pH of the lake water will be calculated by using the following formula:

pH = - log_{10} [H^{+}]

pH = -log_{10} [ 0.00001]

pH = 5
