英文原题:A 200 g water sample is heated from 20℃ to 80℃. The specific heat capacity of water is 4.18 J/(g℃). Calculate the amount of heat energy absorbed by the water sample.相关知识点: 试题来源: 解析 解答:首先计算温度变化ΔT = 80℃ - 20℃ = 60℃。然后利用公式Q = mcΔT...
thetemperaturerise in each material may vary. Because not all substances warm up at the same rate, the sand and water temperatures are different. As a result, the temperature rise for different types of solids varies based on the solid’s composition. This phenomenon is called specific heat ca...
Have a grown-up help you cut off one side of the box. You want to keep the heat energy of lamp enclosed in the area of your experiment as much as possible. Fill one of the cups with sand and the other with water at room temperature. Place the cups side by side in the bottom of...
The specific heat capacity of liquid water is 4.18 kJ/g C, how would you calculate the quantity of energy required to heat 1.00 g of water from 26.5 C to 83.7 C? What is the difference in temperature changes in terms of the specific heat capacities of lead and water? ...
SIR-We were intrigued by the proposal1 that the nearly constant body temperature (around 36 C) of many homoiothermic animals can be explained by the fact that the specific heat of water passes through a minimum around this temperature. The explanation offered was that "an organism functioning ...
用电功量热法测定水的比热容(Determination of specific heat of water by electric work calorimetry) Determination of specific heat of water by electric work calorimetry I. objective requirements 1. proficiency in calorimeter; 2. to measure the specific heat of water by means of electric calorimetry,...
2) A pot of water is heated by transferring 1676kJ of heat energy to the water. If there is 5.00 kg of water in the pot, and the temperature is raised by 80.0 K, what is the specific heat of water? Answer:The heat energy transferred to the water is 1676kJ = 1 676 000 J. The...
What Is the Specific Heat of Water? Some substances heat up quickly, while other substances heat up slowly.Water is one of the latter—it has a high specific heat capacity because it requires more energy to raise the temperature. Water has a specific heat capacity of 4182 J/kg°C.Because...
Metal atoms have fewer degrees of freedom than water molecules and, as a result, require lower thermal energy values for a unit change in temperature. The table below mentions the specific heat capacities of some common metals; water is included as a reference. SubstanceSpecific heat capacity, ...
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) H Hannah Bonville Text 4 Why Does Water Resist Heat Changes? Recall that water is a polar molecule. This means that each water ...
