Which physical quantity is conserved when a planet revolves around the sun?
moment of inertia is conserved.
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
Are all physical changes are reversible changes?
yes , all the physical changes are reversible changes.
Is humidity a physical change?
Changes in humidity are physical, NOT chemical, changes.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
Is mass conserved in both physical and chemical change?
neither physical or changes its property
What are the two physical quantities that are not conserved?
Entropy and work (by non-conservative force ) are not conserved
Which physical quantity is conserved when a planet revolves around the sun?

When metamorphic rock melts and turns into lava is matter conserved?
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
What does it mean to say that a physical quantity is quantized or conserved?
-Joanna Tantay
Why changes of stat are physical changes?
The changes of stat are physical changes because the stat is similar to the physical changes.
Are state changes chemical or physical changes?
Physical Changes
When matter changes state what two things are always conserved?
Mass and chemical composition
How do you conserve physical resources?
The best way to conserve physical resources is to not use them. The less that is drawn from the Earth the more that can be conserved.
What is marijuana physical changes?
what is marijuana physical changes
Are all physical changes are reversible changes?
yes , all the physical changes are reversible changes.
