Answer:
A. The balloons will increase to twice their original volume.
Explanation:
Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:
P ∝ 1/V
P = k/V
PV = k (constant)
P = pressure, V = volume.
Let the initial pressure of the balloon be P, i.e. , initial volume be V, i.e. . The pressure is then halved, i.e.
Therefore the balloon volume will increase to twice their original volume.
False, rivers tend to flow from high ground to low ground
Answer: 325 mg
Explanation:
Grains ---> ounces -----> pounds -----> grams -----> mg
5 gr x (0.00229 oz / 1 gr) x (1 lb / 16 oz) x (454 g / 1 lb) x (1000 mg / 1 g) = 325 mg
