2014年9月8日 · The specific heat capacity, or simply specific heat (C) of a substance is the amount of heat energy required to raise the temperature of one gram of the substance by one degree Celsius. Heat energy is usually measured in Joules ("J") or calories ("cal"). The variables in the equation q = mCDeltaT mean the following: " let:" q="heat energy gained or lost by a …

2015年3月27日 · This equation gives you the amount of heat supplied(Q or E), to a material of mass m and specific heat capacity(c) and this heat causing a change in temperature of the material DeltaT or Deltatheta The Specifice Heat Capacity of a material(c), is the amount of heat energy that causes a change in temperature of 1K or 1°C per kg of that material. Q= …

2017年5月18日 · q = mcDeltaT is correct, but only at constant pressure, but it can be shown that DeltaH = mcDeltaT is also correct. But q ne DeltaH unless we are at constant system pressure. So no, they are definitely not quite the same thing. Neither is more "scientific", whatever that means... q is heat flow in any condition. DeltaH is the change in enthalpy, and is the heat flow …

2018年1月13日 · Re: q=mCdeltaT Post by Lily Sperling 1E » Sat Jan 13, 2018 5:24 pm You could have q=mCdeltaT where "m" refers to the mass in grams and the "C" refers to the specific heat capacity, or you could have q=nCdeltaT where "n" refers to the number of moles and "C" refers to the molar heat capacity.

2015年4月14日 · q=mcDeltaT, in which q is the energy gained or lost, m is mass, c is specific heat capacity, and DeltaT is the change in temperature (final temperature - initial temperature).

2017年3月23日 · q = mcDeltaT (to remember: q equals m-cat) q = heat energy (Joules) m = mass (grams) c = specific heat (("Joules")/("Celsius x grams") ) DeltaT = change in temperature (Celsius) specific heat is the amount of heat required to raise the temperature of one gram of substance by one degree Celsius. It is different for every element/compound and is usually …

2018年4月12日 · Usually "J"/("kg" \\ ^@"C") or "J"/("kg K"). 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. c=("J")/("kg K"), if the temperature …

2017年4月11日 · q = mcDeltaT q = heat energy in joules m = mass in grams DeltaT = change in temperature If you know these values, you can solve for specific heat (c).

2018年7月9日 · I make it approximately 140.29 megajoules. We use the specific heat equation, which states that, q=mcDeltaT where: q is the heat energy supplied in joules m is the mass of the object in kilograms c is the specific heat capacity of the object, here it's in joules per kilogram kelvin DeltaT is the change in temperature Here, DeltaT=3000^@"C" …

2022年1月28日 · I believe that you always use Q=MCDeltaT and you can get either a positive or negative value for Q depending on the value of DeltaT. If DeltaT is positive, it means that the reaction is endothermic and Q will be positive. If DeltaT is negative, then the reaction is exothermic and Q will be negative.
