Answer:
chemical and electrical ( and sometimes nucelar)
Explanation:
Melt chocolate and measure the temperature and then melt wax and measure the temperature and compare his results.
Depends on the cut if its like a pimple You could use chap stick but if its a deep cut you should probably get it checked out/ use a lot of pressure and hold a clean rag over the cut. if its a little scrape clean it with alcohol and put some napkin over it and then a bandaid
Density can be calculated using the following rule:
density = mass / volume
therefore,
mass = density x volume
From the givens:
we have the density = 1030 kg/m^3 and volume = 1.89 m^3
Substitute in the equation to get the mass as follows:
mass = 1030 x 1.89 = 1.9467 x 10^3 kg
If you’re given molecular weight, you know that density is mass/volume. You need to convert the molecular weight to volume. If you know what molecule it is, use the gram formula mass to convert it into grams.
