The final temperature of the sample of gas is 689.65 Kelvin.
<h3>What is the relation between temperature and pressure?</h3>
Relation between the temperature and pressure will be represented by the ideal gas equation PV = nRT, and for this question required equation is:
P₁/T₁ = P₂/T₂, where
P₁ & T₁ are the pressure and temperature of the initial sample.
P₂ & T₂ are the pressure and temperature of the final sample.
Pressure is in mmHg and on putting values from the question on the above equation, we get
T₂ = (810)(390.8) / (760) = 416.5 degree C = 689.65K
Hence required temperature of the sample is 689.65K.

Answer:
D. The piece of bread travels with straight- line horizontal acceleration.
Explanation
Answer:
The light emitted by a light bulb is a form of radiation that occurs when the filament heats up and its thermal emission gains enough energy to move into the visible spectrum.
Explanation:
Light bulbs contain a filament which is heated up electrically. When this filament is heated up,energy in the form of heat is imparted to the electrons in the filament.
This thermal excitation of electrons ultimately leads to emission of light in the viable spectrum. This light is now radiated through a light bulb.
Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. ... Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours.
