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.
How do you find mass when given volume temperature and heat capacity?
This question requires density to answer. Density is a ratio of mass to volume, and is dependent on temperature. Materials do have variable density based on temperature. The equation for density is mass/volume.
