GradeBuddy is best used as a supplement to your own notes, not as a substitute.◦ There is a container of (freezing cold) liquid nitrogen, and there is a (room temperature) balloon. When the balloon is placed into the liquid nitrogen, it condenses (withot popping). These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.◦ The volume decreased because the molecules began to move slower. ◦ The temperature of the balloon outside of the liquid nitrogen:▪ Has a larger velocity of molecules▪ Has more pressure inside▪ Is less dense◦ The temperature of the balloon inside of the liquid nitrogen:▪ Has a smaller velocity of molecules▪ Has less pressure inside▪Is more dense*Mass doesn't change, only the temperature does.Temperature ScalesFahrenheit Celsius Boiling Point 212°F 100°CFreezing Point of Water at SeaLevel32°F 0°CScales Meet -40°F -40°CEnergy-Energy: The ability to do work- Kinetic Energy has to do with motion.◦ Example: Drop of a rainfall; a bullet moving- Potential Energy has to do with stored energy◦ Example: Droplet inside of a cloud; latent heat stored in water vapor; foodThese notes represent a detailed interpretation of the professor’s lecture.
