Yes, the mass of a sample of water remains unchanged when it expands. This is because only its density and volume vary with temperature. As the temperature increases, two dependent changes occur: the volume of the water increases and the density decreases. These two changes happen in correlation with each other such that the mass remains exactly the same.
A second way of thinking about this problem is on a molecule scale. When heating water (composed of many H2O molecules) the number of the molecules in your sample doesn't change, nor does the mass of each molecule. Therefore there is no reason your sample's mass should change (unless you lose some water, which can be prevented by using a sealed container).

If sample of drinking water was contaminated with 15 ppm by mass of chloroform then express in percent by mass?

When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
When water evaporates does its mass increase?
The mass remain unchanged.
When water evaporates does its mass decrease?
The mass remain unchanged.
The volume of a sample of water is 20cm3 the mass of?
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
When a gas or liquid is heated then its mass is?
The mass remain unchanged.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
What happen to a given mass of water as it is cooled from 4° to 0°?
Expands
A sample of 1 mL of water has a mass of about?
The mass of 1 mL of water is 1 g.
A sample of zinc is placed in a graduated cylinder. The initial volume of water= 15.0mL and final volume of water and sample= 24.0mL. Determine the mass of the sample of zinc?
what?
If 213 J raises a sample of water 8.2oC what is the mass of the water?
6.2g
How are mass and energy conserved when water evaporates?
As the more energetic form of water -- water vapor -- is formed, the liquid water chills. Thus conservation of energy is preserved. Mass of course remains the same.
When a substance evaporates what happens to its mass?
Its mass is unchanged.
If 213 J raises a sample of water C what is the mass of the water?
6.2 g
