Spontaneous is no spontaneous
The mass of the blimp is 1.12 kg.
<em>Step 1</em>. Calculate the<em> volume of the blimp</em>.
<em>V</em> = 6.28 × 10⁹ mm³ × (1 m/1000 mm)³ = 6.28 m³
<em>Step 2</em>. Calculate the <em>mass of the helium</em>.
Mass = 6.28 m³ × (0.1786 kg/1 m³) = 1.12 kg
The capacity to do work is said to be energy. It is a quantitative property and conserved quantity. It can exist in different forms such mechanical energy, sound energy, chemical energy etc. According to law of conservation of energy, energy can neither be created nor be destroyed implies there is no loss of energy occurs during any process or any reaction only conversion of energy takes place.
Temperature and pressure are not forms of energy, they are physical properties.
Hence, first option (1) is the correct answer i.e. chemical, mechanical, electromagnetic are three forms of energy.
