0.5L will be the Volume of the gas if the pressure is increased to 540kPa.
According to Boyle's Law, pressure is inversely proportional to the volume of the gas, if temperature and the number of particles are kept constant. That is, an increase in pressure will reduce the volume and vice versa.
If Polaris were to go supernova today, no one currently on Earth ever know it happened because it would take 434 light years to reach the Earth
Explanation:
The Polaris or the North Star that we can see at the North Pole of the Earth in the night historically dates back to 434 years in the past. If the Polaris becomes a supernova or if it dies now, it will take 434 years in the future from now to know about it.
This is simply because ‘one light year is the distance traveled by light in one year’. Hence currently, one cannot know about what happened to the Polaris supernova even if it happens now.
The symbol on a regulatory marker
that indicates hazards such as rocks or stumps is an Orange Diamond. Regulatory
markers are types of non-lateral markers such as white and orange markings that
are used as navigation aids that give directions, warn of dangers and marks
controlled locations. Orange diamond shapes warns of dangers such as rocks,
stumps or construction.
One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.
