What happens to an amount of water when its temperature is reduced from 8°C to 4°C? Its density increses |
its density decreases |
its density remains a constant |
it vaporizes |
Using the equation of density.
And using the ideal gas equation
If the temperature decreases , the volume decreases . and introducing this value in the equation of density , density tends to increase. Therefore the density increases .

Please do the 50 multiple choices questions. NAME CHOICE from 4 c to zero? MULTIPLE water as it is cooled 1. What happens to a given mass of a. expands b, contracts c. vaporizes contracts, nor vaporizes. d. Neither expands, 2. A plate has a hole drilled through it. The plate is put into a furnace and heated. What steel the size of the inside diameter of a hole as its temperature increases? happens to a. increases b. decreases C,...
A sample of water has a temperature of 20.0 °C. Use the following values from Chempendix of the exact density of the water sample Density (20.0) = 0.9982063 g/mL Density (70.0) = 0.97776 g/mL What happens to the density when you heat the water sample to a temperature of 70.0 °C?
Describe IN POINT FORM what happens when you raise the temperature of a sample of water from - 100 to +300 at a constant pressure of 0.5 atm. You'll type in your answer below. MAKE REASONABLE ESTIMATES OF TEMPERATURE AS NEEDED. (Assume that 0.5 atm is about where the little double dashes are on the Pressure axis, below the 1 atm mark and remember, while you do need to be reasonable, you are just taking ESTIMATES.) HO Platin) 218 +...
If a star doubles its temperature but the radius remains the same, what happens to its luminosity?
Conceptual What happens to the temperature when the water reaches its melting point? 1. 1. Create a heating curve of temperature v. time for water in Exploration 1. Select three different colors to represent changes in temperature over time as the heat energy input changes in each of the three trials. How does varying the heat energy affect the resulting temperature v. time graph? You can attach your graph or just state your observation based on the question asked. Conceptual...
A cylinder with a piston is filled with steam and its temperature is maintained by a heat source. When the piston is suddenly pushed down, so as to decrease the volume of the steam, what happens to the pressure inside? not sure Why? a the pressure increases bthe pressure decreases c the pressure remains the same d the pressure first decreases and then increase Comes from 13.3 The Ideal Gas Law
During an isothermal compression, water pressure increases from 33 atm to 66 atm. The water temperature remains constant at 20 C. If the isothermal compressibility is 5.8x10^-5 atm -1, the increase im density is?
how much will the temperature of a cup (180) of coffee at 95 c be reduced when a 45g silver spoon (specific heat 0.24 j/g c ) at 25 c is placed in the coffee and two are allowed to reach the same temperature? Assume that the coffee has the same density and specific heat as water.
When a photon collides with an electron and gives it energy, what happens to the photon after bouncing from the electron? a. the photon frequency remains the same. b. the photon wavelength decreases. c. the photon wavelength remains the same. d. the photon wavelength increases. e. the photon frequency increases.
