Explanation:
Alkanes are the simple hydrocarbons that have only carbon and hydrogen atoms attached to each other through single bonds.
General chemical formula of an alkane is , where n is any integer.
For example, if n = 5 then formula of the alkane will be as follows.
=
=
A suffix "-ane" is added in the name of an alkane. So, an alkane with five carbon atoms will be known as pentane.
Answer : The water's temperature change will be,
Explanation : Given,
Density of water = 0.998 g/mL
Volume of water =
(conversion used : 1 L = 1000 mL)
Specific heat of water =
Heat absorbed =
(conversion used : 1 kJ = 1000 J)
First we have to determine the mass of water.
Now we have to calculate the change in temperature of water.
Formula used :
where,
Q = heat absorbed by water
m = mass of water
= specific heat of water
= change in temperature
Now put all the given value in the above formula, we get:
Therefore, the water's temperature change will be,
