Question

What do you mean by isothermal process ???​What do you mean by escape velocity ?

❤✌Vanshika, gagan✌❤​

Answer 1

1) In thermodynamics, an isothermal process is a type of thermodynamic process in which the temperature of the system remains constant: ΔT = 0. In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).

2) In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it.

Hope it will helps ✌

Answer 2

Answer:

Examples of Isothermal Process

Changes of state or phase changes of different liquids through the process of melting and evaporation are examples of the isothermal process. ... A refrigerator works isothermally. A set of changes take place in the mechanism of a refrigerator but the temperature inside remains constant.

Explanation:

In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it. Escape velocity rises with the body's mass (body to be escaped) and falls with the escaping object's distance from its center. The escape velocity thus depends on how far the object has already traveled, and its calculation at a given distance takes into account the fact that without new acceleration it will slow down as it travels—due to the massive body's gravity—but it will never quite slow to a stop.

A rocket, continuously accelerated by its exhaust, can escape without ever reaching escape velocity, since it continues to add kinetic energy from its engines. It can achieve escape at any speed, given sufficient propellant to provide new acceleration to the rocket to counter gravity's deceleration and thus maintain its speed.
