Answer:
When the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy
Explanation:
The answer that "the entropy will is increases" is correct as:
The water at 90° C i.e at higher temperature is mixed with the water at 10° C i.e the water at the lower temperature.
The water at lower temperature will have molecules with lower energy while the water with higher temperature will have molecules undergoing high thermal collisions. Thereby, when the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy.
Therefore, the answer is correct with respect to the water at lower temperature.
Meanwhile, for the water at higher temperature , the temperature of the system will decrease. Thus, the entropy of the water at higher level will decrease.
Answer:
Contact force is a force that requires a contact between two bodies and is ubiquitous in nature
Explanation:
The force is distributed in two categories i.e
Contact Forces are the forces which is requires a contact between two bodies to occur.
The Types of contact forces are given below:
- Tension Force
- Normal Force
- Air Resistance Force
- Applied Force
- Spring Force
Some common daily examples of the contact force are
- Frictional force between the tyres of a moving vehicle and the road.
- Air flowing in opposite direction of a moving object.
- Pushing a table with hand and the friction between its base and floor.
- Stretching a rubber band with hands etc.
Also non-contact forces are Gravitational force, Electrical force and Magnetic force.

Hello there!
In this case, according to the given chemical reaction, it is first necessary to compute the moles of reacting LiOH given its molar mass:

Thus, since there is a 1:1 mole ratio between lithium hydroxide and silver nitrate (169.87 g/mol) the resulting milligrams turn out to be:
