What is the heat capacity of water at stp?
The heat capacity of water at standard temperature and pressure (STP) is typically expressed as its specific heat capacity, which is about 4.18 joules per gram per degree Celsius (J/g°C) for liquid water. This value indicates the amount of energy required to raise the temperature of 1 gram of water by 1°C. It's important to note that heat capacity can vary slightly with temperature and pressure, but this value is commonly used for liquid water at STP.
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
What properties of water protects organism from overheating?
water has a high heat of vapourization.it absorbs much heat as it changes from liquid to gas.it has the capacity of absorbing heat with minimum of change in its own temperature
What liquid would be the most difficult to raise and lower the temperature of?
One with a high heat capacity
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
Does Liquid ammonia have a higher heat capacity than liquid water?
No, liquid water has a higher heat capacity than liquid ammonia. Water has a high specific heat capacity due to its hydrogen bonding, which allows it to absorb and release heat more effectively than ammonia.
How does the phase of water affect its specific heat capacity?
Typical heat capacities are (exact values depend on temperature): Solid (Ice): 2.108 kJ/kg·K Liquid (water): 4.187 kJ/kg·K Gas (water vapor/steam): 1.996 kJ/-kg·K In comparison - you can see that liquid water has a higher heat capacity that ice or steam.
How do you compare the liquid water's heat capacity to most materials at the earth's surface?
Higher

How do you determine specific heat capacity of a liquid?
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.
What is the specific heat capacity of liquid aluminum?
The specific heat capacity of liquid aluminum is approximately 0.9 J/g°C.
The specific heat capacity of a liquid by an electrical heating method?
To determine the specific heat capacity of a liquid using an electrical heating method, you can measure the change in temperature of the liquid when a known amount of electrical energy is supplied. By using the formula Q = mcΔT (where Q is the heat energy supplied, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the temperature change), you can calculate the specific heat capacity of the liquid.
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
Molar heat capacity of water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
