Air becomes hot on a sunny day primarily due to the sun's radiation. When sunlight reaches the Earth's surface, it warms the ground, which in turn heats the air directly above it through conduction. Additionally, the warm ground causes air to rise, creating convection currents that distribute the heat. As this process continues, the overall temperature of the air increases.

Which best explains why a hot air balloon rises into the air?
A hot air balloon rises into the air primarily due to the principle of buoyancy, which states that an object will float if it displaces a volume of fluid (in this case, air) that is heavier than itself. When the air inside the balloon is heated, it expands and becomes less dense than the cooler air outside. This creates an upward force, allowing the balloon to ascend. The greater the difference in temperature between the hot air and the surrounding air, the higher the balloon will rise.
When the weather is sunny and bright how is the air pressure?
When the weather is sunny and bright, air pressure tends to be higher. High pressure systems are generally associated with clear skies and calm weather conditions.
When one ascends in the atmosphere the air becomes?
When one ascends in the atmosphere, the air becomes thinner, which means the molecules are more spread out, leading to lower air pressure. Additionally, the temperature typically decreases as you go higher in the atmosphere due to the decrease in density and energy of the air molecules.
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
What becomes of this water vapour as hot air rises?

When air is warm, it rises and leaves an area of low pressure which becomes filled with sinking cold air. After a hot, sunny day, the land cools faster than the sea. What is likely to happen after a hot, sunny day on the sea shore?

Which gas law best explains why a hot-air balloon floats in the air?
The ideal gas law helps to explain why a hot-air balloon floats in the air. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air. This creates a buoyant force that allows the balloon to float.
What is the best air conditioner in the middle east?
I think it should be Nissan sunny ...cheap and best...the new compressor is cheaper than the old one
What is the best weather to fly in for hot air balloons?
The best weather to fly is on a sunny day. However there should be minimum wind. Wind can cause dangerous accidents.
Which gas law best explains diving medical problems such as air or sinus squeeze?
Boyle's Law."Squeezes" are caused by the effects of pressure on trapped air spaces.
Which best explains why insulators keep heat in and cold out?
fire also warms the air around it by convection.this warmed air then moves through the room and heats it by conveection

Why is it foggy in the morning on a sunny day?
Fog can occur in the morning on a sunny day when the ground cools overnight and the air above it becomes saturated with moisture. As the sun rises and heats the ground, the moisture in the air condenses into fog. The presence of fog does not necessarily mean it will be a cloudy day since the fog usually dissipates as the temperature rises.
What gas properties best explains the ability of air bags to cushion the force of impact during a car accident?
gasses are compressible
As air becomes warmer it becomes less?
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
Which property of gases best explains the ability of air bags to cushion the force of impact during a car accident?
Gasses are comperssible (plato)
What Air Force airpower tenet explains that a single commander focused on the broader aspects of an operation can best mediate the competing demands for air and space support against the strategic and?
Centralized control
