Given that the gas inside the balloon is an ideal gas, then the ideal gas equation can be used to describe the system. I think the correct answer from the choices listed above is option B. If the balloon is heatedto a temperature of 15.5T while it is placed under a high pressure of 15.5P, then the volume of the balloon stays the same since the change in temperature corresponds to same degree of change with pressure.
Sedimentary Rocks.
The other types of rocks are igneous, formed by magma, and metamorphic, formed from other rocks changed through heat and pressure.
The mass number of an isotope is determined by the number of neutrons in the isotope plus the number of protons.
For instance Carbon-13 is an isotope of carbon. The "13" is the mass number of the isotope.
So, in this example, 13 = #protons + #neutrons
Explanation:
This means that when the gas in a hot air balloon is heated, the gas expands. The balloon has a fixed volume, but there is a hole at the bottom. So, the extra volume flows out of the hole in the bottom of the balloon. Since there is less air in the same volume, its density decreases
