So what you dos is the final temperature - the initial temperature. For example for 1) we have 88.5 celsius degrees - 78 celsius degrees = 10.5 celsius degrees.
1.) Precipitate is formed
<span>2.) Odour </span>
<span>3.) Heat is emitted ( change in temperature) </span>
<span>4.) Formation of a Gas</span>
Answer : The volume of a solution is,
Explanation : Given,
Mass of = 75.0 g
Molar mass of = 125 g/mole
Molarity = 3.5 mol/L
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of a solution is,
To create the liquid and superfluid states you cool down helium gas to a few degrees above absolute zero
Answer:
It depends on the weather.
Explanation:
Like rain and hail, snow comes from the water vapor that forms the clouds, but obviously its formation is different: snow forms when the temperature is low in the atmosphere. In these conditions the water vapor drops freeze and when they collide form tiny crystals that join together to form snowflakes, which fall to Earth when they are heavy enough.
