Answer:
She will observe that the pressure on the tire is higher.
Explanation:
By the ideal gas law, the pressure and the temperature are directly proportional, so, if the temperature increases the pressure increases too:
PV = nRT (P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature).
The temperature is a measure of the average kinetic energy of the gas molecules, so when the temperature increases, the energy also increases, and the gas molecules will move more quickly, so they will collide more often between themselves and in the wall. Those collisions will be with more force because the velocity is higher.
So, the pressure will be higher, because it is the result of collisions of the gas molecules with the walls of the tire.
Answer:
Explanation:
It makes sense because Helium and Hydrogen only hold 1 and 2 subsequent protons/neutrons and electrons. When the Big Bang happened the entire universe was so hot that it was impossible for elements to form since it was impossible for electrons to stay bound to the atoms. After a few seconds the universe began to cool enough for electrons to bond to atoms and create different elements. Since Helium and Hydrogen have 1 and 2 electrons subsequently we can assume that they were the first elements to be created. Also they are the most abundant elements in the Universe which backs up this theory.
Answer:
the three point problem is well known as the in structial
Explanation:
ccording to Michigan State University, heat is created when molecules in the liquid move in different directions and bang into one another. These fast moving particles hit the side of the container where they are located. Heat conduction causes the heat from the liquid to be transferred to the container. The container gets hotter while the liquid gets colder. The liquid also loses heat as the surface area is exposed to air. The air gets heated while the container and the cup cool down.
A thermos container keeps liquids hot because the tight lid prevents heat from escaping the container. The core of the thermos is also filled with insulation, which does not conduct heat as well, so the liquid inside the cup does not cool down as quickly. Most thermos containers also feature reflective exteriors that limit the heat lost to radiation. A Styrofoam cup is made up of 95 percent air. This air conducts heat, which draws the warmth from the liquid into the cu
