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.

P2 = 40 atm
Explanation:
Given:
P1 = 2 atm
V1 = 1200 L
V2 = 60 L
P2 = ?
Using Boyle's law and solving for P2,
P1V1 = P2V2
P2 = (V1/V2)P1
= (1200 L/60 L)(2 atm)
= 40 atm
Answer: First, here is the balanced reaction: 2C4H10 + 13O2 ===> 8CO2 + 10H2O.
This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.
Next, let's determine how many moles of butane are burned. This is obtained by
5.50 g / 58.1 g/mole = 0.0947 moles butane. As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947 = 0.1894 moles CO2.
Now we need to figure out the volume. This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions: 273 K and 1 atmosphere.
We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).
V = 0.1894 x 0.082 x 273.0 / 1 = 4.24 Liters.
Explanation:
The strength of electrical forces tells about the size of charge on the object.
<h3>What is infer about the strength of electrical forces?</h3>
The strength of the electric force between two charged objects depends on the amount of charge that each object have and on the distance between the two charges. When the amount of charge gets bigger, the force also gets bigger, and when the distance between the two charges gets larger, the force also gets smaller. Electric forces are the attraction present between two charge bodies.
So we can conclude that The strength of electrical forces tells about the size of charge on the object.
