A scientist adds heat to each of the following substances.The one that<span> will probably absorb the most heat before its temperature changes significantly is
</span> 50 g of liquid water
because water has larger heat capacity
so correct option is C
hope it help
<span>Percentage
by mass is the amount in mass of a component in a mixture per 100 unit of mass of the
total mixture. Percentage by mass is the same as %w/w. We can determine this by dividing the mass of the solute with the total mass of the mixture. However, from the problem statement, we are given the volume of the water so there is a need to convert this value to mass by using the density of water. We calculate as follows:
Mass of solution = 100 mL (0.99993 g/mL) water + 25 g EtOH
Mass of solution = 124.993 g solution
%w/w = 25 g / 124.993 g x100
%w/w = 20% of EtOH</span>
Given mass of tungsten, W = 415 g
Molar mass of tungsten, W = 183.85 g/mol
Calculating moles of tungsten from mass and molar mass:
This is the process of sieving, in which the heavier particles settle at the bottom and the lighter ones are retained at the top.
