WebTo answer the title of your question, yes it is not only customary, it is necessary to express heat loss as a negative number, but the question still has to be phrased correctly--using … WebThe specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is …

Specific heat of a substance can be - Toppr Ask

WebApr 24, 2010 · Yes, metallic lithium experiences negative specific heat as it is heated from cryogenic temperatures. This results in a crystalline state change. This is known as the heat of reversion.... WebHeat capacity of a substance can be negative as we can see in hydrogen it velocity increases if we take out its energy velocity is related to temperature (Maxwellbotzmann … daily wire bill maher

energy - Positive vs. negative heat of solution confusion

WebIf you work out the math then the heat associated with a negative change in temperature gives the heat a negative sign. It'll have the same magnitude as the same increase in temperature, just different signs. WebOct 22, 2006 · That is not the definition of specific heat capacity. This formula is exactly wrong. Let me show you. In any reaction, the sum of the heat gains is zero. Some will lose heat (negative gain), and some will gain. Heatgainedbywater+ heatgainedbyboject=0 Now if you solve this, it is always correct. WebDec 3, 2016 · As T → 0 the spacing is greater than k T, and the end result is the solid has no accessible degrees of freedom and therefore a zero heat capacity. However the moment you add the smallest amount of heat the temperature increases, some states become accessible and the specific heat becomes non-zero. daily wire bill clinton
