Mario uses a hot plate to heat a beaker of 50mL of water. He used a thermometer to measure the temperature of the water. The wat
er in the beaker began to boil when it reached the temperature of 100 C. If Mario completes the same experiment with 25mL of water, what would happen to the boiling point?
The boiling point decreases as the volume decreases.
Explanation:
The Temperature - Volume law otherwise called as Charles law is applied, which says that the volume of the given gas at constant pressure is directly proportional to the temperature measured in Kelvin. As the volume increases, the temperature also increases, if the volume decreases, then the temperature also decreases.
As per the Charles law, here the volume is decreased from 50 ml to 25 ml so the boiling point also decreases.
as long as he's using pure water, there will be no change to the boling temperature. boiling point depends on the purity of the substance, not volume. so the temperature at which mario's water boils remains 100C.
To calculate the volume of any rectangular shape, We can simply multiply length to wide and to depth. Let d be the depth. 15 x 6 x d = 216 d = 216 / 15 / 6 d = 2.4 Therefore the depth is 2.4m
Answer: The volume of the solution formed will be 32.5 L. Explanation: Molarity is defined as the amount of solute present in 1 L of solution. The equation used to determine molarity of the solution follows: We are given: Molarity of the solution = 0.02 mol/L Mass of NaCl = 38 grams Molar mass of NaCl = 58.5 g/mol Putting values in above equation, we get: Hence, the volume of the solution formed will be 32.5 L.
