For this question, I would definitely say an article containing documented experiments and data because if you are talking about something to do with science, you should use science to prove your point. People usually believe articles done by someone who did the experiment themselves rather than quoting other people from their findings.

Considering the chart shown, at what temperature does the substance boil? 200ºC 1,200ºC 2,200ºC 2,400ºC
kodGreya [7K]

Answer:

The answer is 2,200ºC

Explanation:
I took the assignment for Edge, I don't think I can send the image because it might pick up on that and get reported, sorry!

The only other rationale that I have is that it's boiling because the graph shows that it's at a constant temperature/rate at 2,200ºC for quite a while. Typically when something boils, it stays at that constant rate of boiling, unless you turn the temperature up or it's finally able to peak..?

An copper mass is heated and placed in a foam cup calorimeter containing 45.0 mL of water at 24.0 degrees celcius. The water rea
Alenkinab [10]

Answer:

= 9,593.1 Joules

Explanation:

Heat absorbed by water is equivalent to heat released by copper.

Heat absorbed is given by;

Q = mcΔT

where m is the mass, c is the specific capacity and ΔT is the change in temperature.

Therefore;

Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.

Heat absorbed by water = 45 g × 4.18 J/g°C × 51

                                         = 9,593.1 Joules

Therefore, the heat released by copper is 9,593.1 Joules
