a pound of water will weigh the same as a pound of chocolate
What happens to the mass of ice as it melts into water? Nothing. The mass stays exactly the same. Mass can be defined as the amount of matter present in an object, and no matter is added to or taken away from ice as it changes into its liquid state, water. However, interestingly, the DENSITY (or the way the mass is distributed throughout the object, defined as mass per volume or g/mL) does change as ice becomes water. As ice melts to water, its density increases. Another way of looking at it is, as water freezes to ice, its density decreases. This is why ice floats on water! (If this weren't so, the worlds climate and environment would be drastically different -- think of the polar ice caps...) _______________________________________________________________________ But it is true that : ice weighs 0.92 g/mL and water is 1 g/mL so technically there is a difference Thank you George. Just to clarify a minor point, those values you gave aren't weight, but density. Ice doesn't "weigh" 0.92 g/mL, that value is its density. The density of ice is 0.92 g/mL The density of water is 1 g/mL Density is a measurement of the way an objects weight is distributed in a volume. When a block of ice with a certain mass melts into water, the mass of the water is EXACTLY the same. What changes is the volume occupied by the water when the ice melts. So, as far as weight, or mass, is concerned, there still is technically no difference.
Yes, there are graphs showing the solubility of NaCl in water vs temperature and pressure. At room temperature and standard pressure, NaCl solubility is around 36 g per 100 ml water. As temperature increases, solubility also increases. Pressure has a smaller effect on NaCl solubility compared to temperature. A graph can illustrate these relationships visually.
There is no direct conversion between liters and pounds of soil as they are measuring different properties (volume vs. weight). To convert liters to pounds, you would need to know the density of the soil. You would multiply the volume in liters by the density of the soil to get the weight in pounds.
Salt water pools typically maintain a similar temperature to chlorine pools since the method of sanitization (salt vs. chlorine) does not significantly affect the water temperature. Other factors, such as sun exposure, time of day, and climate, have a greater impact on the water temperature of the pool.
Solubility of NaNO3 is 1.25 kg/kgwater. There are solubility vs temperature curve of many sodium salt available in the internet and text book.

Weight vs volume. PLace object in container already full of water. Measure volume of liquid displaced. weight object. weight divided by volume equals density
None. Freezing will not change the mass of a substance. However, it might change the density of a substance, thus making something heavier or lighter for the same volume.Water has a lower density when frozen (ice) than when it is liquid. Therefore the same volume of ice will weigh less than the same volume of liquid water.Again, if you have a certain amount of anything and freeze it, the mass WILL NOT change!
i like dark chocolate best :)but i like milk chocolate ;J
Sure, Look up the solubility of sodium chloride in water vs alcohol.
Usually, the one that is solid has a higher molecular weight
Oh, dude, you're talking about water! Yeah, water is like the rebel of the chemistry world. Most substances get all cozy and closer together when they freeze, but not water. It's like, "Nah, I'm gonna spread out and be less dense as ice." So yeah, water is that cool kid who breaks all the rules in the solid vs. liquid density game.
Milk vs the candy.
Three minutes without chocolate. One hour with chocolate
land vs water is land against water
Yes some cats do but it depends on what sort of chocolate it is Do not give your cat chocolate! Chocolate is poisonous to both cats and dogs. It contains theobromine, a stimulant which they are unable to metabolize properly. At best it will make them sick, at worst it will kill them.
Determining which country eats the most chocolate is a complicated question. You see, the amount of chocolate consumed is not directly proportionate to the volume or weight of a chocolate bar. My wife used to work for Hershey's and their chocolate was low in chocolate. And then, there is the question of white chocolate vs milk chocolate vs dark chocolate? that's not even considering the amount of hot chocolate. choc·o·late [ chókələt, chóklət ] (plural choc·o·lates) Definition: Food or flavoring, typically a smooth sweet brown solid, made from roasted and ground cacao seeds usually sweetened and mixed with cocoa butter and dried milk. Chocolate is made into bars or candy, or used to flavor other foods, especially cakes, desserts, sauces, and cookies. Chocolate comes in varying amounts of cacao (the word for chocolate). The amount of cacao in any one type of chocolate is expressed as a percentage of the overall volume or weight. Determining the amount consumed depends on not only the volume or weight of the various chocolate types, but also the percentage of cacao contained in the chocolate product. One can contribute to the answer to this question by eating a chocolate bar now! According to a survey by Chocolate Manufacturers Association, Switzerland leads the world in chocolate consumption with 22.36 pounds per person. Austria and Ireland are not far behind with 20.13 pounds and 19.47 pounds, respectively. In 2005 Germany was the largest consumer of chocolate with each person eating an average of 11.12 kilograms of chocolate that year. Definitely a European country; most surveys point to Switzerland as being the largest consumer worldwide. The United States imports most of the chocolate in the world, but the Swiss eat the most chocolate per person.
