A weather balloon is inflated to a volume of 29.5 L at a pressure of 742 mmHg and a temperature of 23.0 ∘C. The balloon rises in the atmosphere to an altitude where the pressure is 400. mmHg and the temperature is -15.3 ∘C. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
