CARE ACTUAL EXAM 2026
◉ Name the four ways in which heat can be transferred. Answer:
conduction, convection, radiation, evaporation and condensation
◉ How do you convert Celsius to Fahrenheit? Answer: F=
(1.8xC)+32
◉ What is sublimation? Answer: Transition from solid to gas
without passing through the liquid state
◉ Which law states: the pressure inside the bubble varies directly
with the surface tension of the liquid and inversely with its radius?
Answer: Laplace's law
◉ Which term means "a phenomenon in which a liquid in a small
tube moves upward, against gravity" Answer: capillary action
◉ What is absolute humidity? Answer: the measured weight of
water vapor extracted from air using a drying agen (measured in mg
water vapor/L gas)
,◉ What is relative humidity? Answer: the ratio of actual water vapor
content to its saturated capacity at a given temperature
◉ What theory states: gas molecules travel about randomly at very
high speeds and with frequent collisions Answer: Kinetic theory
◉ What does Avogadro's law state? Answer: 1-g atomic weight of
any substance contains exactly the same number of atoms,
molecules, or ions
◉ What is Avogadro's constant? Answer: 6.023 x 10^23
◉ What does Graham's law state? Answer: the rate of diffusion of a
gas is inversely proportional to the square root of its gram molecular
weight
◉ What does Dalton's law state? Answer: the total pressure of a
mixture of gases must equal the sum of the partial pressures of all
component gases (law of partial pressures)
◉ What does Henry's law state? Answer: at a constant temperature,
the amount of a given gas that dissolves in a given type and volume
of liquid is directly proportional to the partial pressure of that gas in
equilibrium with that liquid (solubility of gases in liquids)
, ◉ What does Boyle's law state? Answer: with constant temperature,
volume and pressure are indirectly proportional (as one increases,
the other decreases)
◉ What does Charles law state? Answer: with pressure constant, the
volume of a gas is directly proportional to its temperature
◉ What does Gay-Lussac's Law state? Answer: pressure exerted by a
gas varies directly with its absolute temperature
◉ What does the Bernoulli principle state? Answer: as flow
increases, the pressure in fluid will decrease along with its potential
energy
◉ The Venturi effect is an application of which principle? Answer:
Bernoulli principle
◉ What is critical temperature? Answer: the highest temperature at
which a substance can exist as a liquid
◉ Which term means: "an approach to determining optimal clinical
management based on several practices" Answer: evidence based
medicine
