As water is cooled from 4 degrees C to 0 degrees C its density?
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
How density is impacted by the temperature of the heat energy of the material?
An increase in temperature causes thermal expansion which increases the volume. This cause a decrease in density. Except in the case of water between 0 and 4 degrees C, where increased temperature results in a contraction and so increased density.
How much heat is required to raise the temperature to 5.0 mL of water from 2.50 degrees Celsius to 75 degrees Celsius?
Density = grams/ml 1.00 g/ml = X g/5.0 ml = 5.0 grams water ============== q(joules) = mass * specific heat * change in temp. q = (5.0 grams)(4.180 J/gC)(75 C - 2.50 C) = 1515.25 Joules ---------------------------------/4.184 = 362 calories -------------------
Is the relationship linear between density and temperature?
The relationship between density and temperature is linear. In a thermal expansion, density will decrease and temperature increases and vice versa.
Is 1ml of water is equal to 1g?
Yes, 1 milliliter (ml) of water is equal to 1 gram (g) at standard temperature and pressure. This relationship is due to the density of water, which is approximately 1 gram per milliliter. However, this equivalence holds true primarily for pure water at around 4 degrees Celsius.
