Dena’s recipe for lentil soup calls for 150 milliliters of olive oil. Dena wants to triple the recipe. How many liters of olive oil will she need?

Solution

We will find the amount of olive oil in milliliters then convert to liters.

Triple 150 mL
Translate to algebra. 3 · 150 mL
Multiply. 450 mL
Convert to liters. 450 mL · 0.001 L 1 mL
Simplify. 0.45 L
Dena needs 0.45 liter of olive oil.

Convert between u.s. and metric systems of measurement

Many measurements in the United States are made in metric units. A drink may come in 2-liter bottles, calcium may come in 500-mg capsules, and we may run a 5-K race. To work easily in both systems, we need to be able to convert between the two systems.

[link] shows some of the most common conversions.

Conversion Factors Between U.S. and Metric Systems
Length Weight Volume
1 in = 2.54 cm
1 ft = 0.305 m
1 yd = 0.914 m
1 mi = 1.61 km


1 m = 3.28 ft
1 lb = 0.45 kg
1 oz = 28 g




1 kg = 2.2 lb
1 qt = 0.95 L
1 fl oz = 30 mL




1 L = 1.06 qt

We make conversions between the systems just as we do within the systems—by multiplying by unit conversion factors.

Lee’s water bottle holds 500 mL of water. How many fluid ounces are in the bottle? Round to the nearest tenth of an ounce.

Solution

500 mL
Multiply by a unit conversion factor relating mL and ounces. 500 mL · 1 fl oz 30 mL
Simplify. 500 fl oz 30
Divide. 16.7 fl. oz.
The water bottle holds 16.7 fluid ounces.

The conversion factors in [link] are not exact, but the approximations they give are close enough for everyday purposes. In [link] , we rounded the number of fluid ounces to the nearest tenth.

Soleil lives in Minnesota but often travels in Canada for work. While driving on a Canadian highway, she passes a sign that says the next rest stop is in 100 kilometers. How many miles until the next rest stop? Round your answer to the nearest mile.

Solution

100 kilometers
Multiply by a unit conversion factor relating kilometers and miles. 100 kilometers · 1 mile 1.61 kilometers
100 · 1 mi 1.61 km
Simplify. 100 mi 1.61
Divide. 62 mi
It is about 62 miles to the next rest stop.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
