Answer:

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons.

Based on the wave model of light, physicists predicted that increasing light amplitude would increase the kinetic energy of emitted photoelectrons, while increasing the frequency would increase measured current.

A sample of gas is placed in an ice bath so that there is 10 J of heat transfer out of the sample. At the same time, the gas is

rusak2 [61]

Answer:

$\Delta U=-50J$

Explanation:

Hello,

In this case, we use the equation regarding the first law of thermodynamics which is:

$Q-W=\Delta U$

In this case, the want to compute the change in thermal energy of the gas which is related with ΔU. In such a way, since the 10 J are being removed, they are set as negative in the aforesaid equation, moreover, the 40 J of work are positive since it is a work done on the system. Hence:

$-10J-40J=\Delta U\\\Delta U=-50J$

Best regards.
