I need some help. 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

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
