The specific heat capacity of water is 4186 J/kg°C because water requires a large amount of energy to change its temperature due to the hydrogen bonds between water molecules. This property makes water an effective temperature buffer in nature, regulating the Earth's climate and supporting life.
What else can I help you with?
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 is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
Which item the towel the sand or the water - has the highest specific-heat capacity?
Water has the highest specific heat capacity among the three items. This means it can absorb or release a lot of heat energy without undergoing a large change in temperature. Sand and towels have lower specific heat capacities compared to water.
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What is the specific heat capacity of water and alcohol?
The specific heat capacity of water is approximately 4.18 J/g°C, while the specific heat capacity of alcohol (ethanol) is around 2.44 J/g°C. This means it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius, and 2.44 Joules for 1 gram of alcohol.
How much heat is required to heat up 68 g of water by 9 degrees Celsius You must give correct units with your answer?
The specific heat capacity of water is 4186J/kgK First convert your temperature to Kelvins: 9+273.15=282.15K And g to kg: 68g*(1kg/1000g)=0.068kg Now multiply through: 0.068kg*282.15K*4186J/kgK All units cancel except J to get: 80,313J Simplify to 80.3kJ (kilo joules)
When does the thermal capacity of a substance become equal to its specific gravity?
Thermal capacity is equals to the product of the mass of the body and its specific gravity. Thus, specific heat is equals to the thermal capacity divided by the mass of the body. Now, if the mass of tue body be unity then specific heat will be equals to the thermal capacity of the body. So, thermal capacity of unit mass of a substance is equals to its specific heat
What is the specific capacity of water?
At 20°C the specific heat capacity of water is 4.183 J/g °C or 4.183 J/gK.
What has the largest specific heat capacity brick iron water or glass?
Water.
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 substance has the highest specific heat capacity among common materials?
Water has the highest specific heat capacity among common materials.
How is specific heat of a substance different from the heat capacity?
Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater. The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Water has a greater specific heat capacity.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
What is the heat of water?
the specific heat capacity of water is 4200 J / kg °C
Does water or iron has the largest specific heat capacity?
Of those two substances, water has.
is the specific heat of coconut water and water the same?
No, the specific heat of coconut water is typically lower than that of regular water. Coconut water has a specific heat capacity of around 3.91 J/g°C, while water has a specific heat capacity of around 4.18 J/g°C.
