A piston has an initial volume of 1.643 L at a pressure of 128 kPa. The temperature is maintained at 27 oC as the volume is decr

eased to 0.593 L. What is the new pressure in kilopascals?

Answer:

  • <u>355 kPa</u>

Explanation:

The ideal gases follow Boyle's law: at constant temperature pressure and volume are inversely related:

       PV=constant

       P_1V_1=P_2V_2

       P_2=\dfrac{P_1V_1}{V_2}

Subsituting and computing:

     P_2=\dfrac{1.643L\times 128kPa}{0.593L}\approx355kPa

Snowcat [4.5K]

Answer:

THE TEMPERATURE AT WHICH THE CHEMICAL REACTION IS BEING CONDUCTED.

Explanation:

The reaction rate constant is dependence on the temperature in which the reaction takes place. The rate of a reaction and the activation energy relationship is given by the Arrhenius equation with the rate constant as a function of temperature.

Mathematically, the rate constant is expressed as;

k(T) = Ae^-Ea/RT

where Ea is the activation energy, R is the gas constant, Ae is the pre-exponential factor and it is the frequency at which a reactant molecule collide with each other, T is the temperature.

The latent heat of melting is 80 calories for 1 gram of ice. if 1 gram of ice absorbs 60 calories what do i get?
Eva8 [605]
Latent heat of melting is the energy that a solid absorbs to change its phase as its liquid. During this process, since all energy is used to change the phase, the temperature is constant.

Here the latent energy of melting for 1 g of ice is 80 calories and that 1 g of ice only absorbed 60 calories. hence the phase is not changed because it requires more 20 calories to melt.

Hence 1 g of ice remains as its solid phase (ice).
