Let's say I supply heat Q to a system. If it's internal energy increases by U and the work done on it is W then by the first law of thermodynamics, Q = U + W. Now, let's say that due to the thermal expansion, the gravitational potential energy of the system also increases by P. Would it be right to say Q = U + W + P? What if the kinetic energy also increases(by K), is it right to say Q = U + W + P + K

In a constant pressure process, the change in internal energy is

$U=\frac{3}{2}nRT=\frac{3}{2}P(V2-V1).$

However in a constant volume, is the change in internal energy $U=\frac{3}{2}nRT=V(P2-P1)$ ?

$U=\frac{3}{2}nRT=\frac{3}{2}P(V2-V1).$

However in a constant volume, is the change in internal energy $U=\frac{3}{2}nRT=V(P2-P1)$ ?

Are you looking for help understanding the first law of thermodynamics? This fundamental law of physics is essential to understand the transfer of energy and heat. You can find answers to your questions here, as well as some equations to help you understand it better. The first law of thermodynamics is a statement of the conservation of energy. It states that energy can neither be created nor destroyed. This means that the total amount of energy in an isolated system remains constant. You can use this law to calculate the amount of energy transferred or converted in a given process. Whether you are a student or a professional, understanding the first law of thermodynamics is essential. Get help with questions, equations and answers in our math site.
