Answer:
7.01 hope this is right !
Explanation:
This problem can be summarized thusly:
qlost by copper = qgained by water + qgained by calorimeter
2) Therefore:
(610. g) (95.3 °C − x) (0.387 J g¯1 K¯1) = (45.0 g) (x − 36.5 °C) (4.184 J g¯1 °C¯1) + [(10.0 J/K) (x − 36.5 °C)]
Comment: The K and the °C cancel because the °C in this problem is a temperature difference (not one single specific value) and the "size" of one K = one °C.
22497.471 − 236.07x = 198.28x − 7237.22
424.35x = 29734.691
x = 70.1 °C
Freezing. If you take away energy from something, (lower its temperature), it will freeze. If you add heat to something, it will melt if it is a solid and evaporate if it is a liquid.
When you add energy to something, the atoms which comprise the substance jiggle and vibrate, meaning that on a large scale, a solid will become a liquid, and a liquid will become a gas.
How are you going to experiment means how will you show your project in a real life situation like a penny being cleaned with different acids.
