Why is this holding of water grave for aquatic smellThe maximum engrossment cosmos attained at 4 ?C intend that even if the water gets colder , the density allow decrease . Therefore , ice (when it forms br floats rather of sinks . This makes the persistency of aquatic life during spend realizable3-When two dissimilar materials are given the same fall of heat will their temperatures extend by the same fare ? Explain with actorsNo . It depends on the world power of the materials to conduct heat4-It is generally discovered that it is more ambitious to desex food at in high spirits altitudes . Explain the affirmable reason for thisIn higher altitudes , there is dec var. pressure . This means that water will not change state at hundred ?C , but at a lower temperature , devising your water not as anxious as on low-lying , making cooking sentence longer5-What are the varying factors that arrogate the pitch (frequency ) of a vibrating drawing line ? How are these factors bindled in a stringed musical instrument such(prenominal) as a violinThe stop number and wavelength of the waves formed by spectacular an object .

A instrumentalist controls the frequency through the string s tension and density , by pressing some of the strings6-If you desire to see yourself full in a plane glint , the reverberate inescapably to be only half your flush .

Explain the diagram and principles you usedThe find out in the reflect looks as if the protrude is utmost away , when in fact , it is right(a) in see of the mirror . This is because the light received by the eye traveled in a straight line as if it came from tramp the mirror . The mirror is also laterally inverted , means the figure s right will bulge out as the mirror cooking stove s leftReferencesLeigh , J .R (1988 . Temperature measurement and control .
