Explanation

oxygen is delivered by the bulk flow of blood (flow = Q) to the exchange vessels (i.e., capillaries) by virtue of its presence in the blood at concentration [O2]a

increasing blood flow will increase the delivery of oxygen via the blood to the tissues.

Explanation

Saurology is the study of  Lizards.

Explanation

The word 'Geometry' is derived from an ancient Greek word 'geometron'. The word 'geo' means 'Earth' and 'metron' means 'measurement'.

Measurement of the Earth is called Geometry.

Explanation

The rate of evaporation is directly proportional to temperature.

Thus, the rate of evaporation is higher on a warm day than a cold day having low temperature and clothes dry faster on a warm day.

Explanation

Steam has higher energy than boiling water because it possesses the additional latent heat of vaporization.

So, when steam falls on the skin and condenses to produce water it gives out 22.5 x 105 J/kg more heat than boiling water at the same temperature.

Explanation

Water is known to have a higher specific heat capacity which makes it an ideal coolant.

This is because coolant is used to regulate heat in a device

and in order to regulate heat, the coolant must be able to tolerate high levels of heat,

so this is done by water due to its high specific heat.

Explanation

Clay is a poor conductor of heat as compared to wood and bricks.

Therefore, clay neither allows the external heat to enter the house in summer nor allows the internal heat to escape in winter.

Hence, mud houses remain colder in summer and warmer in winter.

Explanation

A hydrogen-filled balloon expands as it rises and may even burst after rising very high in the atmosphere

As one goes high, the weight of the atmosphere above decreases and so does the pressure.

Thus for a balloon filled on the ground, the pressure inside the balloon exceeds that outside and thus it bursts.

Explanation

Vitamin C (Ascorbic Acid)

Acetic acid which is a dilute solution is used extensively as vinegar.

Explanation

A molecule is the smallest unit of a compound

that can exist by itself and retain all of its chemical properties.
