First, we went back to discussing the experiment we did last week with the ethanol and the water. We figured out that ethanol requires less energy for its particles to expand because its less dense.
After that, we came to a consensus that temperature is a measure of the energy of particles, measuring the speed of the particles (velocity). The average velocity (energy) of all of your particles is your temperature!
On Tuesday, we focused on pressure. Pressure is equal to Force(newtons) divided by your Area (meters squared). We measure pressure in Pascals (Pa). According to this formula, if you decrease your area, your pressure increases and if you increase your force, the pressure will increase. Some factors that might affect the pressure of a gas would be the volume of the gas and the temperature. For example:
The pressure of the gas in A would be greater because the volume is less than in B.
On Wednesday, we used a pressure reader thingy and a syringe to find out what happens when you change the volume of the pressure source. We found out that as your volume increases, your pressure decreases. We also had to find the formula of what was going on. We used the inverse and found of that P(pressure)=k(constant)1/v(volume). The k or constant of proportionality equates 2 things. In this case, the constant was the TEMPERATURE. So, Pressure=Temperature/Volume
On Thursday, we had to complete another lab to figure out if you keep the temperature and volume constant but change the number of particles in the volume, what would happen to the pressure. we figured out that if you increase the number of particles in the same amount of volume, your pressure increases.
On Friday, Mr Abud wasn't in class so as a ChemTeam, we had to create a study guide for our quiz on Wednesday.
