Answer:
In an exothermic reaction the energy gained by the surroundings must be <u>equal to</u> the energy lost by the reaction.
Explanation:
Exothermic reactions occur by the loss of energy in the form of heat to the surroundings (apparatus and the system).
The heat gained can be quantitatively analysed and measured provided no product escapes the system and it is numerically equal to the amount of heat lost by the reaction.

That depends on what type of pressure you are attempting to measure, to measure Atmospheric pressure, you would use a Barometer. To measure things like tires, you could use a Tire Pressure Gauge. For Industrial processes and boilers, you would use a Manometer. For pressure vessels, you would use a Bordon Gauge. <span />
Answer:
The amount of force applied to his body is 1944.44 N
<em>The chances of the person dying is very high owing to the high impact force with which the person would experience when he or she lands on the asphalt road due to the jump out of the moving car.</em>
Explanation:
We all know that,
F = Ma where,
F = Force
M = weight of the person
a = acceleration or velocity of the moving car
Therefore;
F = { 70 x (100 x 1000) } / [3600]
= [7 000 000] / 3600
= <u>1944.44 N</u>
