A scientific experiment may be set up in order to test the company's claim.
For this, one may send a number of similar packages from different companies and this one. Then, the time taken for the packages to arrive is noted. Afterwards, difference in time of arrival for the similar packages is calculated and then the data obtained is analyzed. If the company's delivery timings are less than the other companies', then their claim is indeed true.
I am pretty sure that the effect on the volume of 1 mol of an ideal gas is being revelesd by the option : B. The pressure changes from 760 torr to 202 kPa, and the temp. changes from 37degrees C to 155 degrees kelvin. I choose this one because you have to use ideal gas law - V= nRT/P and you will see the doubled pressure in here : <span>760 torr= 1atm and 202kPa = 2 atm.
Do hope it helps! Regards.</span>
Answer:
An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.
Good conductor of electricity
Answer: amount = 2466.95L
Explanation:
given that the speed is = 1900./kmh i.e. 1hr/900km
distance = 1050km
the fuel burns at a rate of 74.4 L/min
therefore the amount of fuel that the jet consumes on a 1050.km becomes;
total fuel used = time × fuel burning rate
where time = distance / speed
∴ total fuel used (consumed) = time × fuel burning rate
total fuel consumed = (1050km × 1hr/1900km) × (60min/ 1hr × 74.4L/1min)
total fuel consumed = 2466.95L
