Hello students.
00:01
So in this question we have been given some subparts of the question and we have to find out which one of the statements are true and which one of them are false.
00:09
So let's start.
00:10
The first statement says that universe is composed of system and surroundings.
00:15
So this is the basic law of thermodynamics.
00:17
A basic definition of thermodynamics of universe.
00:20
That universe is composed of system and surrounding.
00:23
System is something where the reaction occurs and apart from the system, everything other than the system includes the surrounding.
00:34
So our first statement would be a group statement.
00:37
Let's move to the second statement which says that the heat that is released by the surroundings should be absorbed by the system.
00:44
So first of all, this statement is partially correct but we'll consider the statement as false.
00:50
This statement is an incorrect statement.
00:52
Why? because it says that the heat that is released should always be surrounded by system which is not correct.
01:00
The heat that is released in endothermic reaction, the heat is absorbed by the system.
01:07
The system absorbs heat in the endothermic reactions.
01:13
But when it comes to the exothermic reactions, in the exothermic reaction, the heat is given to the system.
01:20
The heat is released by the system in the surroundings.
01:24
So this statement which says that it should be absorbed by the system is not always true.
01:29
The third statement says that in a chemical reaction, energy is lost in the form of heat.
01:35
So this is a true statement.
01:37
Why? because in a reaction, when products are formed, so energy is released when the bond is formed between the products.
01:44
So energy release when the products are formed.
01:47
And there's this energy which is absorbed to break the bond between the reactants.
01:52
So energy that is required to break the bond of reactants.
01:59
When this energy, is less than the energy which is released when the energy released is more than the energy required to break the bond energy is released in the system and this energy is released in the form of heat and light so a statement is a true statement let's move to the next one the next one says the kell present on the label of food products is equal to 4 .184 jules so the statement is definitely a true statement why a simple reason because this is the definition of calorie one calorie is equals to for one calorie contains 4 .184 jules which is most oftenly written as 4 .2 jules also now next one next one says work is the transfer of thermal energy between two bodies that are at different temperatures so our fifth statement is an incorrect statement because this transfer of heat this the transfer of thermal energy between the two bodies at different temperatures suppose there are two bodies, one body is at t2 temperature and one body is at t1 temperature and this temperature t2 is greater than the temperature t1.
03:09
So the thermal energy will be transferred from the t2 object to the t1 object.
03:18
So this is transferred in the form of heat and not in the form of work.
03:22
So this is an incorrect statement.
03:24
Next statement states that a bottled water is an example of isosur.
03:27
So a bottled bottle basically is an insulated boundary from which the transfer of heat is not possible from systems to surroundings or from the surroundings to system.
03:40
And since there is no matter transfer that is occurring between the bottle and the environment, so this statement is going to be a true statement because no matter transfer is no matter is transferred for...
