A hot air balloon has a volume of 15 L when it’s released from sea level, where the pressure is 100 kPa. What will be the hot ai
Lunna [17]

Answer:

65 L

Explanation:

It is assumed that the temperature is constant at both the sea level and the altitude.

<em>According to the gas law, at constant temperature, the pressure of a gas is inversely proportional to its volume.</em> Mathematically:

P1V1 = P2V2 where P1 = pressure at initial volume, V1 = volume at initial pressure, P2 = pressure at final volume, and V2 = volume at final pressure.

In the illustration, V1 = 15 L, P1 = 100 kPa, V2 =?, P2 = 23 kPa

V2 = P1V1/P2 =  100 x 15/23 = 65.22 L

<u>The volume of the hot air balloon at the altitude would be 65 L</u>

Muscle contraction is an example of which of the following types of work? Group of answer choices electrical concentration heat
Citrus2011 [14]

Answer:

Muscle contraction is an example of mechanical contraction.

Explanation:

Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.

Muscle contraction is based on force and length.

The process of skeletal muscle contraction is an energy requiring process.

In order to perform mechanical work,actin and myosin  utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.

In a working muscle,glucose is released  from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
