The price of petrol increases from R10 to R12 a liter while the quantity demanded decreases from 600 liters to 590 liters?

I'm taking a guess at what this question is really asking. I believe you may be asking what the price elasticity of demand is for petrol. This can be calculated two ways which can give you different answers.
The first (point price elasticity) takes the initial price divided by initial quantity demanded and multiplies that by the change in quantity over the change in price. This would look like (10/600)*(10/2)=1/12
The second method is arc elasticity. This requires that you take the average of the prices divided by the average of the quantity multiplied by the change in quantity over the change in price. So (11/595)*(10/2)=11/119

A balloon is filled with helium. Its volume is 4.2L at 312.K. What will its volume in liters be at 285.K assuming no change in pressure?
Assuming pressure is constant, like you said, volume and temperature have a direct relationship. As temperature increases, volume increases; as temperature decreases, volume decreases. Setting up a algebraic direct proportion, you get approximately 3.84 liters for the balloon at 285 degrees K.
What determines the volume of gas?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
What determines a gas's of volume?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
Why elasticity of demand is measured in percentage?
Price elasticity can be precisely measured by dividing the percentage change on quantity demanded by the percentage change in price that caused it. Thus e can measure price elasticity by using the formula Price elasticity = Percentage change in quantity demanded ÷ percentage change in price
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
What is the quantity of 47 liters expressed in cubic meters?
47 liters equates to 0.047 cubic meters.* liters x 0.001 = cubic meters
Is 14 and 6 proportional if it decreases 7 and 3?
14:6When divde by 2 both sides;7:3This is the answerTwo quantities are inversely proportional when one is multiplied or divided by any number, the other is divided or multiplied by the same number.The relation is also commonly denoted as:y ∝ x−1The graph of two variables that are inversely proportional is a hyperbola.Speed and time are inversely proportional because as the speed increases, the time it takes to reach the destination decreases.Examples3 workers build a wall in 12 hours. How long would it have taken for 6 equally productive workers?In this example, the number of workers and the time are inversely proportional, because when the quantity of people decreases, the total time increases and when the quantity of people increases, the total time decreases.Follow these steps to complete an inverse proportionality word problem:Write down the ratio using one type of term (number of workers or time).Write down the ratio with the second type of term (number of workers or time).Invert one of the ratios (flip it upside down).Cross-multiply, divide and solve (the same method used for direct proportions).It takes 14 hours for a faucet with a flow of 18 liters per minute to fill a reservoir with water. How long will it take if its flow is reduced to 7 liters per minute?In this example, the flow and time are inversely proportional, because when the flow decreases, the total time increases and when the flow increases, the total time decreases.
How many millimeters are in 144 liters?
You measure length in millimeters and capacity/quantity in liters. So, they do not make sense if you mix them.
How does the volume of a gas vary?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
