What is the equation linking density, mass and volume? |
Density = mass/volume p=m/v |
Yo mama |
|
|
What are the symbols and units for: density, mass, volume? |
Density = p - kg/m³ Mass = m - kg Volume = v - m³ |
Your probably gonna fail :) |
|
|
Descrive the sate of matter of a solid |
The particles in a solid are in a fixed arrangement and they vibrate rapidly |
Why do you try? |
|
|
Descrive the state of matter of a liquid |
Particles move more freely than a solid but are still in contact and can take any shape |
WOLF GANG |
|
|
Describe the state of matter of a gas |
The particles can move freely through the air there are no forces of attraction between them |
Naega pyeonghae |
|
|
Why is change of state referred to as a physical change and not a chemical change? |
Change in state of matter is a physical change because of the physical condition and appearance changes but not the chemical composition |
MATERIOL GWORRRLL 😍💅✨ |
|
|
Describe the displacement technique used to determine the volume of an irregular shaped object. |
Fill a measuring cylinder will water and put in your irregular shape then measure the displacement of water |
I hate physics |
|
|
When substances change state, there mass is conserved. What does this mean? |
The mass of the substance does not chnage once it has changed state. |

|
Describe how to determine the volume of a regularly shaped object e.g a cube |
Width×length×height |
Your dumb if you dont know this |
|
|
What is an internal system? |
Energy shared by the particles within it |
Namjoon fat tits |
|
|
Define internal energy |
Total kinetic energy and potential energy that makes that system |
WOOF WOOF BARK |
|
|
What are some factors that affect the increase of temperature of a system? |
1) the reactant particles move more quickly 2) they have more energy 3) the rate of reaction increases 4) the particles collide successfully more often |
Work harder if you wanna live in France with Ava and your nct baby |
|
|
Explain the differences in density of solids, liquids and gases |
In general, solids are denser than liquids, which are denser than gases. The particles in a solid are touching qihting very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances of space between them |

|
Define specific heat capacity |
The specific heat capacity of a substance is the energy needed to raise temp of 1kg by 1°C |
Johnny |
|
|
What is the equation linking change in thermal energy, mass, specific heat capacity and temperature? |
1)⚠️E=mc⚠️🚫 2)Q=mc⚠️T 1)⚠️= heat change M=mass C=specific heat capacity ⚠️🚫=change in temp |
Mark maximus |
|
|
What are the units and symbols for the following: energy, mass, specific heat capacity, temperature change |
Energy = J - joules Mass = m - kg, g Specific heat capacity = C - J/(kg.k) or J/(kg°c) Temperature change = ⚠️🚫 - k or °c |
Your ugly |
|
|
After a long journey, the temperature of a car tyre increases. What is the effect on the gas particles within the tyre? |
The gas particles will gain more kinetic energy, therefore they will move around more. |
Koyas hot |
|
|
Name these bitches Solid - liquid Liquid - gas Gas - liquid Liquid - solid Solid - gas |
S ‐ L = melting L - G = evaporation G - L = condensation L - S = freezing S - G = sublimation |
If you get these wrong your ******* stupid |
|
|
Define latent heat |
Hidden heat - energy required without changing temperature |
Bussy |
|
|
What is the equation linking energy for a change of state, mass and specific latent heat? |
E=mL |
|
|
|
Write the symbol and unit for specific latent heat |
L = (J/kg) |
AHHHHHHHHHHHHHHHHHHHH |
|
|
Describe the difference between specific latent heat of fusion and specific latent heat of vaporisation |
Specific latent heat of fusion - heat needed to chnage from solid to liquid at a constant temp. Specific latent heat of vaporisation is the same thing but just a liquid to a gas |
🐺🐺🐺🐺🐺 |
|
|
Distinguish between specific heat capacity and specific latent heat |
Specific latent heat means, the amount of heat energy needed to convert a phase completely to another phase of a unit mass of a substance. Heat capacity is dependent on the amount of substance |
🙏🙏🙏 |
|
|
What is the equation for pressure and volume |
Pv=constant |
I just wanna die already :) |
|
|
What are the symbol and units for pressure and volume |
Pressure = p (pa) Volume = v (ml, L) |
:) |
|
|
Explain the effect of ana increase in temperature on the pressure of a gas in a container |
The temperature of a gas is proportional to the average kinetic energy of its molecules. Faster moving particles will Collide within the container or small frequently and with greater Force. This causes the force on the walls of the container to increase the pressure increases |
🙂🤞 |
|
|
Explain the effects of an increase of volume on pressure |
When the particles are under pressure they travel faster and hit th walls of the container more frequently. When the pressure is release the kinetic energy of the particles decrease because there Is more space for the particles to move around |
🐶 |
|
|
When work is done on a gas, what effect is there on the internal energy of the gas? |
The internal energy increase |
Bitch |
|
|
When work is done on a gas what effect can there be on the temperature of the gas? |
The temperature increases because the kinetic energy increases |
