Answer:
400 cm³
Explanation:
Let p₁ Pa be the original pressure of the gas
p₂ Pa be the new pressure of the gas
V₁ m³ be the original volume of the gas
V₂ m³ be the new volume of the gas
According to Boyle's Law,
p₁V₁ = p₂V₂
p₁ × 0.0002 = 1/2 p₁ × V₂
0.0002 = 1/2 × V₂
V₂ = 0.0004
∴ The new volume of the gas = 0.0004 m³ = 400 cm³
the element is Ca with atomic number 20

The first law of thermodynamics states that the change in the internal energy of a system equals the net heat transfer into the system minus the net work done by the system. This is another way of saying that energy can neither be created nor destroyed, but it can be converted from one form to another form.
A tea kettle that is warmed on an electric stove is receiving heat energy, this heat energy increases the kinetic energy of the water particles in the kettle and makes them to move faster. As time goes on, the water begins to turn into vapors. The heat energy that is released into the system is been used to carry out the work of evaporation and the whistling of the kettle.
