Which thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged?
egoroff_w [7]
Isothermal process<span> is a </span>change<span> of a </span>system<span>, in which the </span>temperature<span> remains constant: Δ</span>T<span> = 0. So, if the thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged than this process is isothermal. 
</span><span>The Joule's second Law states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. So, isothermal processes are of great interest for ideal gasses.</span>

A 1.5 kg copper block is given an initial speed of3.00m/s on a
ankoles [38]

Answer:

a. 0.01 C

b. dissipated to outside environment

Explanation:

Let the specific heat of copper be 0.3846 kJ/kg-K or 384.6 J/kg-C

(a)The original kinetic energy of the block is:

E_k = \frac{mv^2}{2} = \frac{1.5*3^2}{2} = \frac{1.5*9}{2} = 6.75 J

As 85% of this kinetic energy is converted to block internal heat energy, with specific heat we can calculate the rise in temperature:

E_h = 0.85E_k = 0.85*6.75 = 5.7375 J

mc_c\Delta T = 5.7375

1.5*384.6\Delta T = 5.7375

\Delta T = \frac{5.7375}{1.5*384.6} \approx 0.01^oC

(b) the remaining 15% energy would probably be dissipated to outside environment as heat energy
