Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
Is aniline soluble in ether?
Aniline (phenylamine) is only slightly soluble in water (3.6g/mL @ 20C). This is a volatile amine. It would be similar to trying to mix benzene with water, or any other typical household solvent/degreaser with water. You would see a separation of the liquids into layers.
A thimbleful of water at 100c has a highrer temperature than a swimming pool full of water at 20c but the pool has more thermal energy than the timble explain?
To raise the temperature of water in a thimble of water from 0 to 100 requires a small amount of thermal energy. To do the same with a swimming pool would require putting a huge amount of thermal energy into the water comparatively speaking.
What happens to a glass of water at a temperature of 20C when it is placed into a freezer set at 10C?
The temperature of the glass become also 10 0C.
How is head related to water pressure?
Hydrostatic head (ft) multiplied by the fluid density, and divided by 2.31 equals PSI. The fluid density of water is 1 at normal temperature (20C).
Will Rubidium chloride dissolve in water?
Yes. It has a solubility of about 91g/100mL of water at 20C.
I you wish to warm 100 kg of water by 20 degrees C for your bath show that the amount of heat is 2000 Calories?
100kg of water by 20c for your bath, show that 8370 kJ
If you have 80 grams of NaCl in 100 grams of water at 20 C is that undersaturated saturated or oversaturated?
Oversaturated, only around 35g of sodium chloride will dissolve at that 20C.
Which sample of water has the lowest vapor pressure?
400 mL at 20C
What is 100 degree Celsius minus 20 degree Celsius?
100C - 20C equals 80C
Pour a liter of water at 40c into a loter of water at 20c and the final temperature of the two becomes?
30%
What is the density of water at 20 degress celsius?
0.9982071 g/mL @20C
Which is hotter 20C or 20F?
20c is hotter.
When 418 joules of heat energy are added to 10 grams of water at 20C the final temperature of the water will be?
21
What is the minimum number of notes and coins needed to give 34.85 change?
$20, $10, $2, $2, 20c, 20c, 20c, 20c, 5c
Which is colder -20C or -20F?
-20F
What is the density of water if the temperature is 20 degree Celsius?
0.9982071 g/mL @20C
