Describes how come the ice is floating when you put it into the
water! (refresh your mind on water anomaly)
weight = mg = (V*rho)*g
here,
m = mass
V = volume
rho = density
g = 9.81 m/s^2
since,
density of ice is less than of water.hence ice floats on water.
*reason why ice is less denser :
in liquid state, water molecules are closely held togather by weak hydrogen bond.
in solid state, molecules becomes stable and arranged far from each other. This causes ice to be less denser and hence floats on water.

Suppose you put some water in your ice-cube tray and then place the tray in the freezer. Consider a single ice cube that starts out as 31.0 ml of liquid water at 20.0°C. To determine the energy that must be removed from the water to convert it to an ice cube, we must consider the process in three stages. For stage 1, determine how much energy must be removed from the water to cool it to water at 0.00°C Enter...
A 0.25g ice cube is put into a thermos with 20.0g of
10.0°C water.
Will the ice cube increase or decrease in temp?
Will the water increase or decrease in temp?
will the two changes be equal? why?
what will the final temperature be?
I have this as a lab hmwk. I'm not sure
how to go about answering this because it feels like I'm missing
information.
Should I be using The specific heat of water? How would I find...
Water and ice are mixed together in a glass and have come to equilibrium with each other. The glass is in a warm room. In a period of S minutes 0.024 kg of the ice melts. The latent heat for the ice-water transition is L 3.3 x 10 What is the change in entropy of the water-ice mixture during this process? Answer in . kg Answer: Save response
(e) sugar disappears when stirred into hot water 6. (a) Based on your personal experience, pre a piece of ice in a glass. har experience, predict what would happen if you put cooking oil, water, and (b) Add lines and labels to the figure to illustrate your prediction. (c) If the materials are available, test your prediction. Do the results of your test match your prediction? Briefly explain.

I put some ice at 0c into a styrofoam cup containing 250ml of water at 20.0c. If the final temperature of the water is 4.0c and the density of the water is 1.00g/ml, what mass of ice did I add?
An 12 g ice cube at -19?C is put into a
Thermos flask containing 100 cm3 of water at 20?C. By how much has
the entropy of the cube-water system changed when a final
equilibrium state is reached? The specific heat of ice is 2200 J/kg
K and that of liquid water is 4187 J/kg K. The heat of fusion of
water is 333 × 103 J/kg.

Fill the ice mold with tap water and put it in a freezer for
24 hours. Remove the
mold from the freezer, loosen the ice but do not remove the
ice and place the mold upside
down in a thin paper plate and place the plate on a thick
coffee table or dining table (see
Figure 1). Wait for about 30 minutes, using the cell-phone or
digital watch as a timer, and
then measure the amount of water in the...
An ice cube floats in a beaker of ice cold water. Since the water is ice cold, the ice cube is not melting and hence its volume is not changing. The density of water and ice are, respectively, ρw = 1,000 kg/m3 and ρi = 917 kg/m3. (Assume one of the ice cube's faces is parallel to the water's surface.) (a) If the ice cube is 17.0 mm on each side, how far below the surface (in mm) is the...
