When the temperature of ice-cold water is increased slightly, does it undergo a net expansion or net contraction?
miss Akunina [59]

From the freezing temperature up to about 4°C (39°F) the water CONTRACTS.  That is, it becomes MORE dense.  I think I read that water is the ONLY known substance whose solid phase floats in its liquid phase.  That's why the cubes float in your soda and bergs float in the ocean.  And if weren't so, then life on Earth would not be possible !  Oceans and lakes would freeze from the bottom up, ONE TIME, and then never thaw again.

What is the relation between inertia and mass?
aleksandr82 [10.1K]

Answer:

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Calculate the mass of wood that has the same energy as 1 g of oil
san4es73 [151]

2.3 grams of wood has the same energy as 1g of oil.

The majority of wood and wood waste used as fuel in the United States is used by industry. Manufacturers of paper and wood products are the biggest industrial users. They produce steam and electricity from waste from paper and lumber mills, which saves money by lowering the number of other fuels and electricity they need to buy to run their facilities.

There are numerous power plants that primarily burn wood to produce electricity in the electric power sector, and some coal-burning power plants burn wood chips along with coal to cut down on sulfur dioxide emissions. The primary purpose of wood consumption in the business sector is heating.
