Answer:
Reactant concentration, the physical states of the reactants, surface area, temperature and the presence of catalyst.
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.

Answer:
pH = 11.7
Explanation:
<u>Given:</u>
[OH-] = 0.00500 M
<u>To determine:</u>
pH of the solution
<u>Explanation:</u>
pH refers to the H+ ion concentration in a given solution whereas pOH indicates the OH- ion concentration.
pH and pOH are related by the following equation:
![pH + pOH = 14 ------(1)](https://tex.z-dn.net/?f=pH%20%2B%20pOH%20%3D%2014%20------%281%29)
Here:
![pH = -log[H+]\\\\pOH = -log[OH-]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%2B%5D%5C%5C%5C%5CpOH%20%3D%20-log%5BOH-%5D)
When OH- = 0.00500 M
![pOH = -log(0.00500) = 2.30\\](https://tex.z-dn.net/?f=pOH%20%3D%20-log%280.00500%29%20%3D%202.30%5C%5C)
Based on equation(1):
![pH = 14 - pOH = 14 -2.30=11.7](https://tex.z-dn.net/?f=pH%20%3D%2014%20-%20pOH%20%3D%2014%20-2.30%3D11.7)
Answer:
New volume = 105.6 mL
Explanation:
Given that,
Temperature, T = 240.0 K
Pressure, P = 670 mm Hg
Volume, V = 128 mL
New temperature = -75°C = 198 K
We need to find the new volume. Let it is V'. The relation between volume and the temperature is given by :
![V=kT\\\\\dfrac{V}{V'}=\dfrac{T}{T'}\\\\V'=\dfrac{VT'}{T}\\\\V'=\dfrac{128\times 198}{240}\\\\V'=105.6\ mL](https://tex.z-dn.net/?f=V%3DkT%5C%5C%5C%5C%5Cdfrac%7BV%7D%7BV%27%7D%3D%5Cdfrac%7BT%7D%7BT%27%7D%5C%5C%5C%5CV%27%3D%5Cdfrac%7BVT%27%7D%7BT%7D%5C%5C%5C%5CV%27%3D%5Cdfrac%7B128%5Ctimes%20198%7D%7B240%7D%5C%5C%5C%5CV%27%3D105.6%5C%20mL)
So, the new volume is equal to 105.6 mL.
