What is the relationship between volume and pressure for a gas?
QveST [7]

Answer:

There exists a relationship between pressure and volume through Boyle's Law. It states that when temperature is held constant in thermodynamic syatems, the volume increases as the pressure decreases (and is true the other way around).

What factors could have affected your results?
AleksandrR [38]

Answer:

See below  

Step-by-step explanation:

heat gained by metal + heat lost by water = 0

           m₁C₁ΔT₁           +         m₂C₂ΔT₂         = 0

C₁ = -(m₂C₂ΔT₂)/(m₁ΔT₁)

The factors determining C₁ are

  • mass of water
  • temperature change of water (T_f - Ti)
  • mass of metal
  • temperature change of metal (T_f - Ti)

Any factor that makes the numerator higher or the denominator lower than what you thought, will give a calculated C₁ that is too high (and vice versa).

The major sources of uncertainty are probably in determining the temperatures, especially the initial and final temperatures of the metal. However, you will have to decide what the principal factors were in your experiment.

For example, did the metal have a chance to cool during the transfer to the calorimeter? How easy was it to determine the equilibrium temperature, etc?

Which of the following gives the definition of ion-dipole attraction? Select the correct answer below: O a. lon-dipole attractio
frez [133]

Answer:

D

Explanation:

Anions are attracted to the positive end of a dipole, while the cations are attracted to the negative end. As the size of the dipole moment or the ionic charge increases, the vastness of the attraction also increases. This type of attraction is important for solutions of ionic substances in polar liquids.

Bob adds heat to a substance. When enough heat is added, A. its particles move closer together and the substance becomes a gas.
Elena L [17]

Answer:

C. its particles move farther apart and the substance becomes a gas.

Explanation:

A. is wrong because moving closer together creates a solid, not a gas.

B. is wrong because moving father apart creates a gas, not solid.

C. is correct because moving farther apart creates a gas.

D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.

- Just know the states of matter and how the particles move and that will help with this problem.
