Compared to a swimming pool filled with water, a hot cup of coffee has higher temperature, but less thermal energy
Julli [10]
Thermal energy equation is;
    Q = mcΔθ

Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference

the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.

How is technology useful and how is it harmful
Lelu [443]

Explanation:

The aggregation of methods used in order to accomplish a goal is called technology.

Whether technology is used to accomplish a goal which society does not deem acceptable then the goal is bad. The same technology can be used to do good. So, the question whether technology is harmful or useful depends on the goal a person wasts to acheive.

Let us take an example

The internet is one of the greatest discoveries of mankind which allows people access to unlimited information. It can be used for a variety of different services such buying goods and services. However, the internet is also a technology that facilitates illegal activities that circumvents government intervention. This way of technology being used is harmful.

5.080 x 1016 molecules of hydrogen (gas) to moles
morpeh [17]
Take note that one mole of any substance is equal to 6.02 x 10^23 molecules. Thus in converting 5.080 x 10^16 molecules of hydrogen to moles, just divide it with the Avogadro’s number. The answer would be 8.44 x 19^-8 moles... 

i think that's it :P :)
