Which statements best describe conduction? Check all that apply.

Gennadij [26K]

The statements that best describe conduction are

-Conduction can occur within a substance or between two substances.

-Fast-moving molecules collide with slow-moving molecules.

-Thermal energy is transferred from a warmer substance to a cooler substance.

Explanation :

-Conduction can occur within a substance or between two substances.

Conduction can occur within a substance, but the heat will transfer by conduction only when those parts of the substance are at different temperatures.

For example, when we hold a metal rod over a flame, the end which is in direct contact with the flame becomes hot first. As we continue to heat, the other end of the rod also becomes hot because heat gets transferred through the rod by conduction.

Similarly heat can also be transferred between 2 substances which are in direct contact with each other.

In the above example, when a person is holding the other end of the rod, their hand might burn. In this case heat is transferred between 2 objects ( rod & hand) which are in direct contact by conduction.

-Fast-moving molecules collide with slow-moving molecules.

When an object heated, the molecules gain thermal energy and start vibrating. These vibrating molecules transfer their kinetic energy to neighboring molecules which are at lower temperature and hence are slow moving. This transfer occurs till both of them attain the same temperature.

-Thermal energy is transferred from a warmer substance to a cooler substance.

Thermal energy is always transferred from a warmer substance to a cooler substance. In conduction mode, heat is transferred by transfer of kinetic energy from fast moving molecules to slow moving molecules.

Describe the relationship between the mass volume and density of material

Ilia_Sergeevich [38]

Answer: For a given mass and volume, how much physical space a material takes up, of an object or substance, the density remains constant at a given temperature and pressure. The equation for this relationship is ρ = m / V in which ρ (rho) is density, m is mass and V is volume, making the density unit kg/m3.

Explanation: Hope that helps

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize

Rina8888 [55]

Answer:

Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.

So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.

Equation: $P_{1} V_{1} = P_{2} V_{2}$

Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.

So basically Temperature and volume are directly proportional.

Equation: $\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }$

Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.

Basically, Temperature and Pressure are directly proportional.

Equation: $\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }$

Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.

Meaning the moles (amount of gas) is directly proportional to volume.

Equation: $\frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} }$ (n stands for moles)

There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.
