16. A 1-kg mass of iron is heated through 1000 0C. Find the increase in its rest mass. Specific heat of iron is 500 Joule per kg per 0C
You have to show us your attempt to solve it, up to the point where you are stuck. Do you have any idea what formula(s) you can use? (Is there a formula that relates energy to mass?) Do you understand the concept of specific heat? If not, you should start by looking it up on Wikipedia or something.roopak.arya said:Question. A 1-kg mass of iron is heated through 1000 0C.

Rest mass, also known as invariant mass, is the mass of an object when it is at rest. It is a fundamental property of an object and is independent of its motion or frame of reference.
The increase in rest mass is calculated using Einstein's famous equation, E=mc², where E is the energy of the object, m is its rest mass, and c is the speed of light in a vacuum. The increase in rest mass is equal to the energy of the object divided by the speed of light squared.
An increase in an object's rest mass can be caused by the addition of energy to the object, either through motion or through a change in its physical state. This can also occur through interactions with other objects, such as in nuclear reactions.
Special relativity states that an object's mass increases as its speed approaches the speed of light. This means that as an object's energy increases, so does its rest mass. This phenomenon is known as relativistic mass and is a key aspect of Einstein's theory.
Calculating the increase in rest mass is important in many fields of science, including particle physics, astrophysics, and nuclear energy. It helps us understand the fundamental properties of matter and energy and how they are related. This knowledge also has practical applications, such as in the development of nuclear technologies and understanding the behavior of particles in high-energy environments.
