It is a well-known fact that water has a higher specific heat than iron. Now, consider equal masses of water and iron that are i
nitially in thermal equilibrium. The same amount of heat, 30 calories, is added to each one. Which statement is true? A. They remain in thermal equilibrium
B. They are no longer in thermal equilibrium; the iron is warmer
C. They are no longer in thermal equilibrium; the water is warmer
D. It is impossible to say without knowing the exact mass involved
E. It is impossible to say without knowing the exact specific heats
It is known that water has a higher value of specific heat as compared to iron, therefore, water requires high heat to raise the temperature of both water and iron by the same amount
If the same amount of heat is given to the same mass of different nature then iron will be warmer because its heat capacity is low so less heat can raise more temperature compared to water
The property of matter that will keep the body in motion when the car comes to a halt is the inertia force.
Inertia is the ability of a body to remain in static position. It is the tendency to remain in a stable condition where there is no motion.
Newton's first law is the law of inertia and it states that a body remain in a state of rest or of uniform motion unless acted upon by an external force.
The ability to remain in state of rest by a body is predicated on the force of inertia.
