Explanation: The specific heat capacity of ice is equal to 2.03J∘C.
Q. Are J kg K and J kg C the same?
Assuming you mean kJ/(kg K) and kJ/(kg C), where K stands for a unit on the Kelvin temperature scale and the C for a unit on the Celsius temperature scale, the answer is yes because the Celcius and Kelvin scale have the same unit but different zero points. Normally we use K.

Q. What is J kg K?
Joule Per Kilogram Per Kelvin (J/kg-K) is a unit in the category of Specific heat. This unit is commonly used in the SI unit system. Joule Per Kilogram Per Kelvin (J/kg-K) has a dimension of L2T-2Q-1 where L is length, T is time, and Q is temperatur. This unit is the standard SI unit in this category.
Q. Which metal has highest specific heat?
The metal with highest specific heat is
- A. Be.
- B. Al.
- C. Ag.
- D. Au.
- Solution. Out of the given four metals, Be has highest specific heat (metal with lowest atomic mass will have highest specific heat).
Q. What is the specific heat of plastic?
| Product | Specific Heat – cp – | |
|---|---|---|
| (Btu/(lbm oF)) (kcal/(kg oC)) | (kJ/(kg K)) | |
| Plastics, foam | 0.3 | 1.3 |
| Plastics, solid | 0.4 | 1.67 |
| Platinum, 0oC | 0.032 | 0.13 |
Q. How do you find the specific heat of water?
The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.
Q. Why is the water wet?
“Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each …
Q. Why is the specific heat of water important?
A high specific heat of a substance means that a large amount of heat is required to raise the temperature of the substance. Water covers around 70% of the Earth’s surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature.
Q. Why is the high specific heat of water important to Earth quizlet?
The high specific heat of water helps to 1) moderate temperature in coastal areas, 2) stabilize ocean temperatures, creating a favorable environment for marine life, 3) because it covers most of the earth it keeps temperature fluctuations within the limits for life, 4) helps organisms (that are made primarily out of …
