Since you're giving us the original and final volumes, as well as the mass, and all you want to know is density, we don't actually care about temperature or pressure. Let um do whatever they want to do.
The new mass is the same as the original mass ... 4 grams.
The new volume is 50 cm³.
The new density is (mass)/(volume) = (4g) / (50 cm³) = <em>0.08 g/cm³</em>
The first law of thermodynamics says that the variation of internal energy
of a gas is equal to the amount of heat Q supplied to the gas minus the work W done by the gas:
The variation of internal energy of a gas is:
As it can be seen, it depends only on the variation of temperature
. Since for an isothermal process
, then
. This means that the first law of thermodynamics becomes
and since the work done is 370 J, then the amount of heat is also 370 J:
.
During the roller coasters ride through the top of the hill, it begins to gain PE through a machine. It then will beginning ride down the hill causing the gaining of speed. Furthermore, the roller coaster began to gain KE, although it will lose its PE due to losing its height. Kinetic Theory states that the higher the molecules vibrates the higher the temperature, specifically the higher the speed of the roller coaster, the higher the temperature of its wheels cause from friction! Hope this helps
Answer:
A) a scientific theory or principle
Explanation:
A Theory or principle has to explain different observations for a specific phenomenon. Theories are tested in base of new data to see if they can fit with all the new variations. They gain more acceptance in the scientific world if they predict in a correct way the result of many observations.
For example the uncertainty principle which state that the position and the momentum of a particle can not be known at the same time. Many experiments that aim to test the Uncertainty principle demonstrated this property, but tests are currently being done with other variations to see if the principle still fits with them.
A.) Cubic meters is your answer
Cubic meters are used to measure the volume of solids.
