Answer:
If we add warm water, to the aquarium the dissolved oxygen will dissociate and move into the atmosphere again, leaving the least percentage of oxygen into the water (as it is known that the solubility of gases in water goes down as the temperature rises). Therefore, fishes will have difficulty in breathing in the absence of oxygen and will die.
Answer:
Sonia flies from Sharjah to India via Dubai. She has to spend a lot of time at the airport and on airplanes. She leaves Sharjah at 6 pm on Friday and arrives in Dubai the next day. After a 2 hours stopover, she leaves for India at exact noon. She arrives in Delhi at 1 am. She returns to Sharjah after a refreshing holiday. She takes the same route on her flight back. But this time her stopover in Dubai is one hour less than what it was the last time. Including her layover, her average speed while in the airports and airplanes was 180 mph. Considering the time difference between these places, what is the distance between Delhi and Sharjah in kilometers? Dubai is 4 hours ahead of Sharjah, and 2 hours behind India.
