Step 7: Put the Metal in the water and Measure Temperature Changes (Copper) Initial temperature of metal = 100°c
Initial temperature of water = 22.7°C
Final temperature of both
24.6°C
Subtract to find the temperature changes
for the water and the metal.
AT (water) = 1.9
AT (metal) = -75.4

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
