0 C = ? K | 273 |
Standard units of: temperature (social), temperature (physics), energy, mass, density, length, area, volume, speed, acceleration, force, pressure, and specific heat capacity | °C, K, J, kg, kg/m³, m, m², m³, m/s, m/s², N, Pa, and J/kg °C |
Density and pressure equations | ρ=m/v, p=F/A |
Pressure direction of effect and equation of height | Pressure acts in all directions, p=hρg |
kelvin temp of a gas is proportional to the | avg KE of its molecules |
What happens when a solid melts to form a liquid? | Thermal energy is converted into kinetic to break the particles apart and allow them to move freely, then after melting the thermal just transfers straight to the liquid |
How do particles behave in solids, liquids, and gases? | Solids: locked together, evenly spaced, usually most dense, vibrating. Liquids: freely flowing over each other, can be poured. Gases: take up whole volume of container, bouncing off molecules and the walls, exerting an outward pressure. |
whats specific heat capacity | the energy required to change the temp of an object by 1 degree c per kg |
Change in thermal energy equation | ?Q=mc?T |
What temperature is absolute zero and what does it mean? | -273°C or 0K, particles have 0J kinetic energy and are at a complete standstill. There is no colder temperature as energy=0 |
Gas temperature/volume pressure equations | p₁/T₁=p₂/T₂, p₁V₁=p₂V₂ |
