Why are the freezing points of water and the melting point the same

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

Aphysical change is a change in the size, shape,, or stafe of matter true or false

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
