Both atm and mmHg are pressure units.
mmHg is millimeters mercury, in this pressure is calculated by the height of mercury level.
1 atm is equivalent to 760.0 mmHg
therefore 0.250 atm is equivalent to - 760.0 mmHg/atm x 0.250 atm 
pressure in mmHg is - 190 mmHg

Correct me if I'm wrong, anyone who is more informed on this than I am, but wouldn't it be because of the magnetic fields and whatnot? The longer I think on it, the more I feel like I'm wrong, so don't take my word for it 100%

LenaWriter [7]

Answer:

The term conclusion best illustrates the given statement.

Explanation:

Conclusion refers to a decision or judgment that can be acquired by reasoning. From the observation mentioned in the given table:  

1. The steel, aluminum, and bronze took 27, 45 and 80 seconds to dissolve small section of wax, this signifies that more time will be needed by them to transfer heat to the food while cooking. Thus, food will take more time to cook in them.  

2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.  

After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.

<u>Answer:</u> The amount of heat absorbed by the solution is 2.795 kJ

<u>Explanation:</u>

To calculate the mass of water, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of water = 1 g/mL

Volume of water = [70 + 70] = 140 mL

Putting values in above equation, we get:

1g/mL=\frac{\text{Mass of water}}{140mL}\\\\\text{Mass of water}=(1g/mL\times 140mL)=140g

To calculate the heat absorbed, we use the equation:

q=mc\Delta T

where,

q = heat absorbed

m = mass of water = 140 g

c = heat capacity of water = 4.186 J/g°C

\Delta T = change in temperature = T_2-T_1=(28.74-23.97)^oC=4.77^oC

Putting values in above equation, we get:

q=140g\times 4.186J/g^oC\times 4.77^oC=2795.4J=2.795kJ

Hence, the amount of heat absorbed by the solution is 2.795 kJ
