If youâve got a piece of furniture that youâd like to revamp yourself, take a look at Porterâs Paints industrial Lustre range, particularly the colour âBase Metalâ, and slap it on a stool, old lamp or side table.
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.
The law of conservation of mass (from Lavoisier) states that mass can be neither created nor destroyed (but it may change its form into something that is not desired, such as heat with an engine) or that in a chemical reaction, the total mass of the reacting substances is equal to the total mass of products formed.
