Questions and Answers List

level questions: solids, liquids and gases

QuestionAnswer
0 C = ? K273
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 equationsρ=m/v, p=F/A
Pressure direction of effect and equation of heightPressure acts in all directions, p=hρg
kelvin temp of a gas is proportional to theavg 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 capacitythe 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 equationsp₁/T₁=p₂/T₂, p₁V₁=p₂V₂
