What is the difference between strong acids and bases versus weak acids and bases?
In strong acids and bases, the solute's ions go to completion and dissolve in the solution. In weak acids and bases, the reaction does not go to completion, and they will dissolve only slightly.
In strong acids and bases, the reaction does not go to completion, and they will dissolve only slightly. In weak acids and bases, the solute's ions go to completion and dissolve almost completely in the solution.
In strong acids and bases, there is no reaction. In weak acids and bases, there is a strong chemical reaction.
In strong acids and bases, the pH is lowered after the reaction. In weak acids and bases, the pH increases after the reaction.

We want to calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. the air temperature is 20 oc, canary’s body internal and surface temperature is 33oc, external body surface convective heat transfer coefficient is 25.2 w/m2 .k, temperature difference between the inhaled and exhaled air is 4.3 oc, the ventilation rate is 0.74 cc of air per second, specific heat of air is 1.0066 kj/kg. k and density of air is 1.16 kg/m3 . assume the canary’s body to be a cylinder with 7 cm diameter and 9 cm length, and heat exchange is from the side as well as the top and bottom of cylinder. calculate 1) the net rate of heat lost by radiation, assuming heat gained by the bird through radiation from the surroundings is 11.5 w; 2) rate of heat transferred by convection to the surrounding air; 3) rate of heat transferred in the exhaling air without considering any internal evaporation; 4) total metabolic power.
