Concept explainers
Interpretation:
The function of hot air balloon is to be explained, and the relation between windy coastal weather and Charle’s Law is to be described.
Concept Introduction:
According to Archimedes principle, any object suspended in a fluid, is acted upon by an upward buoyant force which is equal to the weight of the fluid that has been displaced by the object. A hot air balloon with a vacuum inside is lifted by buoyant force because it weighs less than air.
The rising of air due to heat is called convection; the earth is heated unevenly. According to Charles law that part of the air which heats up faster will expand faster, along with a drop in pressure. As the air above the sea is cooler (high pressure), air flows from a high pressure region to the low pressure region.

Initially, the bubble has a volume of 10.0 mL. Assuming none of the air dissolves in the water. how many times larger is the bubble just as it reaches the surface? Use this data: 1. The density of seawater is approximately 1.025 g mL 2. The density of mercury is 13.6 g mL times larger Use your answer to explain why scuba divers constantly exhale as they slowly rise from a deep dive. Since the pressure v by a factor of approximatelyi the volume must v by a factor of approximately i Divers exhale to the amount of gas in their lungs, so it does not V to a volume than the diver's lungs.arrow_forwardAs weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?arrow_forward

Use the combustion of octane as the representative reaction and determine the mass of carbon dioxide (the most significant greenhouse gas) formed per year. The current concentration of carbon dioxide in the atmosphere is approximately 399 ppm (by volume). By what percentage does the concentration increase each year due to fossil fuel combustion? Approximate the average properties of the entire atmosphere by assuming that the atmosphere extends from sea level to 15 km and that it has an average pressure of 381 torr and average temperature of 275 K. Assume Earth is a perfect sphere with a radius of 6371 km.arrow_forward
