Specific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: #q = m * c * DeltaT#, where. #q# - the amount of heat supplied; #m# - the mass of the substance; #c# - the respective substance's specific heat; #DeltaT# - the change in temperature.

2018年4月12日 · Consider the specific heat equation, #q=mcDeltaT# #q# is the energy transferred, usually in joules. #m# is the mass of the object, usually in kilograms. #DeltaT# is the temperature difference, usually in Kelvin or celsius. Solving for #c#, we get, #c=q/(mDeltaT)# Now, we insert in units to figure out #c#.

2014年12月29日 · Specific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: q = m * c * DeltaT, where q - the amount of heat supplied; m - the mass of the substance; c - the respective substance's specific heat; DeltaT - the change in temperature. So, if we want to determine the …

2015年11月24日 · The specific heat of air depends on the temperature. At "250 K"(-23^"o""C"), the specific heat of air is ...

2015年11月25日 · 4.187 kJ/kgK, 2.108 kJ/kgK, 1.996 kJ/kgK for water, ice, and water vapor respectively. The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK.

2017年6月28日 · Cal per gram per degrees Celcius (Cal) / (g*t) where t is temperature in degrees Celcius or (BTU)/(lb*t) where t is in degrees Fahrenheit are common specific heat capacity units. In addition, (kJ) / (kg*t) if you select mass of substance in kilograms and temperature of it in degrees Celcius, is also used. For example, 333 kiloJoules (kJ) will melt 1 kg of ice. 2257 kJ …

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship does not apply if a phase change (a transition between solid, gas and gaseous phases) is encountered, because the heat added or removed during a phase change does not change the temperature. The specific heat of water is 1 calorie/gram °C = …

2015年10月26日 · It is determined experimentally. Specific Heat capacity by definition is the quantity of heat (or energy) needed to raise the temperature of 1 g of a certain element or compound by 1^@C. Therefore, it is determined experimentally. However, there is a relationship between the specific heat capacity s and enthalpy DeltaH, therefore, if we have all necessary …

2017年2月19日 · The greater the value of specific heat, the better the ability of a substance to contain a large amount of heat energy without having to undergo a large increase in temperature. Water, at #4.18 J/(g °C)# has a high heat capacity, which is a main factor in the manner in which the Earth's lakes and oceans affect climate.
