weight?
Teaspoons are a unit of volume, grams are a unit of mass. You cannot convert them without more information.
5 grams of salt in 10 grams of water is more concentrated (50%) compared to 18 grams of salt in 90 grams of water (20%).
After 50 grams of water evaporate, you will be left with 50 grams of water in which the 3.0 grams of salt is dissolved. So, your solution will now contain 3.0 grams of salt dissolved in 50 grams of water.
Depends on the substance. A gram of lead will have a lot less than a ml of volume, while a gram of oxygen will have a greater volume than 1 ml. Water is 1 ml per gram, but that changes with the temperature of the water. Warm water, and very cold water (<4o C) will have a somewhat greater volume than 1 ml per gram weight.
Yes because the water changed its state of matter, but not its actual chemical make up. State of Matter changing is almost always physical change
Assuming that refers to the temperature: the water gets slightly colder.
Without a density or substance to work with, this cannot be determined. If it is water, that would be 1KL for 1,000,000 grams.
Its a physical changed also know as condensation.
The question is incomplete and cannot be answered -- five liters of what?
This cannot be sensibly answered. Milliliters is a measure of volume and grams is a measure of weight or mass.
Impossible to answer ! You cannot add weight to volume !
the gas stays on but the water still doesn't get hot
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, grams is a measure of weight or mass.
Teaspoons are a unit of volume, grams are a unit of mass. You cannot convert them without more information.
It cannot be directly calculated with out knowing the substance. Cups are a measure of volume while grams are a measure of mass. To calculate such problems the density of the substance has to be known.
The flower will die. Water cannot be transported to the flower.
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, grams is a measure of weight or mass.
