A helium balloon in a closed car occupies a volume of 7.7 liters at 68 degrees Celsius. It's a hot day and the temperature rises to 121 degrees Celsius, what is the
new volume of the balloon? Always convert temperature to Kelvin: (Celsius + 273 =
Kelvin)
A)-8.9 L

B)-09.5L

C)-07.7L

D)-8.2 L

there is none because earth is stationary and flat.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
