What happens to the volume of a hot-air balloon when the heater is turned off?

When the heater is turned off, the air inside the balloon cools down, causing it to contract and the volume of the balloon to decrease. This decrease in volume creates less lift, causing the balloon to descend.


What would happen if the volume of gas decreased and then increased?

The temp of the gas would first rise, then drop. If the final volume of the gas is lower than the volume at the start, the temp will be higher than at the start. If the final volume is greater than at the start, then the temp of the gas will be lower than at the start.


How tidal is form?

Is your question Ocean tides? Tidal Waves? Well lets start with tides, tides is caused by gravational pull between two bodies this such as the moon and earth which cause a rise and fall in sea levels. Tidal waves on the other hand is a displacement of mass which causes energy. for example if you have an underwater land slid it displaces a volume of water inwhich creates a shock wave (energy). when this energy wave or displacement reaches shallow water the rise in water level will increase relulting in a tidal Wave.


A semi-detailed lesson plan in respiratory system and it's major parts?

Introduction: Start by discussing the importance of the respiratory system in the body and its role in oxygenating the blood and removing carbon dioxide. Major parts of the respiratory system: Explain the key components such as the nasal cavity, trachea, lungs, diaphragm, bronchi, and alveoli. Discuss their functions and how they work together to facilitate breathing. Demonstration: Show a model or diagram of the respiratory system and explain how air flows through each of the major parts during inhalation and exhalation. Activity: Engage students in a breathing exercise to demonstrate the movement of the diaphragm and expansion of the chest cavity during inhalation. Recap and assessment: Review the major parts of the respiratory system and their functions. Ask students to identify and describe each part to assess their understanding.


Does stroke volume start with increased or decreased preload?

Stroke volume typically increases in response to increased preload, which is the volume of blood filling the heart during diastole. This increased preload stretches the heart muscle, leading to a more forceful contraction and higher stroke volume.
