heat is -----, and temperature is -----.
the total energy in the random motion of molecules and atoms, a measurement of average molecular motion speed.
the ----- system is the most often used in science to measure temperature
heat capacity is
the amount of heat required to raise the temperature of a substance by a given amount.
the heat capacity of water
influences the worlds climate and weather
water becomes----- as it freezes. this is ----- most substances.
less dense, different from
the heat that is lost without a change in temperature when water freezes is called
latent heat of fusion
the heat required to vaporize a substance is called
latent heat of vaporization
the tendency for water to resist temperature change is called -----. it is one of the factors in establishing -----.
thermal inertia, thermal equilibrium
low temperature and high salinity make seawater----- dense.
the ocean is stratified with ----- layers below ----- layers
denser, less dense
the surface zone accounts for approximately ----- percent of the oceans volume
the thermocline is the boundary between layers of water with differing
particles in water----- light, and water ----- light, turning it into heat.
absorb and scatter, absorbs
the ----- zone is the area of the ocean that sunlight never reaches.
the advantage of ocean-based existence over land-based existence, with respect to temperature, is that coolness of the water makes organisms live longer.
false (the advantage is that marine organisms exist in a temperature range that fluctuates less than on land.)
an ----- is an organism with an internal temperature the same as or close to the surrounding seawaters temperature.
the advantage of being an endotherm is
it keeps the metabolic rate the same
sound travels through water ------ in air
about 5 times faster than
hydrostatic pressure has an ----- effect on marine organisms. this is because the pressure inside their tissues is ----- the surrounding pressure.
insignificant, equal to
the ratio between a cells surface and its volume ----- as the diameter increases.
a high surface-to-volume ratio is important to cell function because
it affects the efficiency of nutrients, gas, and wastes passing through the cell membrane
buoyancy affects marine organisms by
minimizing the effect of their weight
the most common adaptation for overcoming water resistance is
drifting with water movement may
carry organsims to new habitats
