Short answer question 1. The figure represents a water molecule. Draw a second water molecule to show how bonds can form between water molecules, including the name of the bond. [2 marks] 2. Water has important solvent properties. Explain these properties using an example to illustrate your a...
Water has a high boiling and freezing point. It boils at 100 C because the strong hydrogen bonds. All these hydrogen bonds between the water molecules need to break for the liquid to change to gas. Water becomes less dense as it gets closer to the freezing point and so ice always forms ...
Specific Heat Capacity of Water at normal temperature and pressure is roughly4.2 J/goC. This means that 1 gram of water requires 4.2 joules of energy to raise 1 degree Celsius. Water has a high specific heat capacity. The actual value of water’s specific heat capacity is4182 J/kg °C. ...
Water has a high specific heat. It takes the addition of a lot of energy to heat up and the loss of a lot of energy to cool down.Explanations (5) Hannah Bonville Text 3 Why Does Water Resist Heat Changes? Recall that water is a polar molecule. This means that each water molecule ...
aWater performs a wide variety of tasks in the body, such as heat capacity, cooling ability, participation in metabolism, pH balance and the major component of all body fluids. 水在身体,例如热容量,冷却的能力、参与新陈代谢,酸碱度平衡和所有体液主要元件执行各种各样的任务。[translate]...
As a liquid, water has more directions to move and to absorb the heat applied to it. There is more surface area that needs to be heated for the overall temperature to increase. However, with ice, the surface area doesn't change due to its more rigid structure. As ice heats, that heat...
Water has remarkable physical properties: Water molecules are polar: one part of the molecule is slightly positive, and the other is slightly negative. Molecules tend to stick together. They also can separate other molecules from each other. — universal solvent; — high density of 1,000 kg/...
Improved apparatus has been developed for measurement of the constant-volume heat capacity Cof condensed phases at low temperatures. The high-pressure calorimeter is closed by a remotely operated valve at the calorimeter and several prob... WR Gardner,JK Hoffer - 《Physical Review A》 被引量: 11...
