Class 09 PSA Quantitative Reasoning Test 01 (2014)

Read the following passage and answer the questions that follow. When solids, liquids or gases are dissolved in a liquid they make a solution. The substance (solid, liquid or gas) being dissolved is called the solute and the liquid that does the dissolving is called the solvent. Solutions which use water as the solvent are called aqueous solutions. When you dissolve a spoon of instant coffee in hot water or add water to some cordial syrup, you are making an aqueous solution. The concentration of an aqueous solution refers to the amount of solute that has been dissolved in a fixed amount of water. For example, if a saline solution (made from salt dissolved in water) has a concentration of 10 g/L, then we know that 10 g salt has been dissolved in 1 litre of water solvent. The concentration of a solution can also be described by the proportion of the solute to solution either by mass or by volume The by mass concentration is used when a solid is dissolved in a solvent. This is calculated by dividing the mass of the solute (in grams) by the mass of the solution (also in grams) and the result converted into a percentage. It is important to note that the mass of the solution is equal to the mass of the solute plus the mass of the solvent. One millilitre of water has a mass of 1 gram. When solute is a liquid, the by volume concentration is used. In this case, the volume of the solute is divided by the volume of the solution and the result is again converted into a percentage. It does not matter which volume unites (millilitres, litres or cubic centimetres) are used, provided that the same unit is used for both the solute and the solution. The table below indicated how much sugar can be found dissolved in different beverages. Which of the following statement is true?

An aqueous solution of copper Sulphate was left out in the hot sun. The heat caused some of the water to evaporate from the solution. The original 150 g solution had a concentration of 10% by mass. If the remaining solution has a concentration of 15% by mass, what volume of water evaporated?

Read the following passage and answer the questions that follow. The temperature of a substance indicates how energetic that substance’s particles are. The particles in a hot object are highly energetic, moving rapidly and colliding with each other frequently. The particles in a colder object move more slowly, collide less often and have very low energy. Over the centuries, scientists have created temperature scales to describe how hot or how cold substances are. All temperature scales use the term degree as a basic unit. However, the size of these degrees is different on each of the temperature scales because the scientists who developed them defined the freezing point and boiling points of water in different ways. The most widely used temperature scale is the Celsius scale which defines the freezing point of water as 0 degree Celsius (written as \({0^\circ }C\)) and its boiling point as \({100^\circ }C\). The Newton scale, developed by Isaac Newton in 1700, also defines the freezing point of water as its zero point, but defines the boiling point of water as 33 Newton degrees (or \({33^\circ }N\)). (A Newton temperature N is converted to its equivalent Celsius temperature C by using the equation: \(N \times \frac{{100}}{{33}} = C\) The Fahrenheit scale, which is still used in many parts of the worlds, defines water’s freezing point as \({32^\circ }F\) and its boiling point as \({212^\circ }F\). (A Fahrenheit temperature F is converted into its equivalent Celsius temperature C by using the equation: \(\left( {F - 32} \right) \times \frac{5}{9} = C)\) Scientists describe the point at which the particles of a substance have no energy at all, as absolute zero. The Kelvin scale uses absolute zero as its starting temperature point (0 K). On this scale, water freezes at 273.15 K and boils at 373.15 K. (A Kelvin temperature K is converted into its equivalent Celsius temperature C by using the equation: K – 373.13=C) A Celsius degree is nearly
