Shorter showers, hand washing dishes, rewearing clothing if it isn’t too dirty, not letting the sink run while brushing teeth, eco friendly toilet.
<span>All matter contain heat energy, and it can be seen anywhere as long as it contains mass and occupies space. Heat energy is another form energy that transfers particles in a substance through kinetic energy. One way to transfer heat from one object to the other is through the difference in temperature between two objects.</span>
As a result of temperature regulation within the body of endothermic animals, human bodies are much exposed to the environment than any other endothermic animal which causes human to sweat through their sweat glands and dogs has no sweat glands like that of human
Answer:
The right choice is "burning gas → pan → water → eggs"
Explanation:
Heat will flow from the body of higher temperature to the cooler body.
So, heat will firstly flow from burning gas to pan by conduction then to the water in contact with pan then to the egg present inside the water.
<u>So, the right choice is :</u>
"burning gas → pan → water → eggs"
Solutions for your questions are the following:
1. remaining amount is equal to:960 g : 100% = 30 g : xx = 30 g * 100% / 960 g
= 3.125%
= 0.03125
Now, we use this formula to calculate the number of half-lives:(1/2)ⁿ = x,
so,(1/2)ⁿ = 0.03125
to calculate n, use this equation:
n*log(1/2) = log(0.03125) n = log(0.03125)/log(1/2)
= log(0.03125)/log(0.5)
= -1.505/-0.301
n=5
Ifn = 5T = 15 min
Then
L = T/nL = 15 min/5
= 3 minutes
2. You should pick filtration. It is use to separate heterogeneous mixtures just like in the problem stated.
