You have a rigid tank that contains R-134a at a quality of 0.40 and 200 kPa. Thermal energy is now transferred to the tank from a high temperature source at 35 oC. This energy transfer process contiunes until the tank is at 400 kPa. The initial size of the tank is 0.5 m3. Determine the TOTAL (not specific) entropy change in the source. Give your answer in kJ/K and to FOUR significant digits.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

c. orbital shape i hope this is correct
