Answer:
Tollen's test or silver mirror test is use to distinguish between ketone and aldehyde.
Explanation:
Tollen's test is use to distinguish aldehyde from ketone because Tollen reagent consist of silver nitrate and ammonia and it oxidized aldehydes to carboxylic acid and the silver Ag+ is reduced to solid silver Ag. It form a inner film wall on the tube that look like mirror. Ketone do not react with Tollen reagent and therefore does not form silver mirror on the tube wall.
Answer:
It will increase the kinetic energy of gas particles and hence gas will expand.
Explanation:
According to law, there is direct relationship between temperature (thermal energy) of gas and it's volume. When the pressure of gas is held constant and it's temperature increases then the volume of gas also gets increases.
When the temperature ( thermal energy) of gas increases then the kinetic energy of particles of gas also gets increases due to which particles start to collide with the wall of container and with themselves as well which in turn causes gas to expand.
