Can someone do this fun experiment for me!? Materials:
-Hot Water
-Cold Water
-Foam Cups
-Thermometer
-Measuring Cup
kk, then:
-Gather materials.
-Measure 50 ml of hot water and 50 ml of cold water into separate foam cups.
-Use a thermometer to measure the temperature of hot water and the cold water.
-Pour the hot and cold water into a third foam cup.
-Allow some time for the thermometer to reach a final temperature, then measure the temperature of the water.

kk, after your done please record your temperatures, and that's all! enjoy your 43 points!!

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
