Question

Which of the following are state functions? Select ALL that apply. The temperature of an ice cube. The internal energy of a system. The distance from the front of the PHSC building to AYRS 120. The current balance in your bank account. The volume of an aerosol can. Match each process with whether it is endothermic or exothermic. Ba(OH)2 middot 8 H_2O(S) + 2 NH_4Cl_(s) rightarrow BaCl_2(aq) + 2 NH_3(aq) + 10 H_2O_(l) Al(s) + Fe_2O_3(s) rightarrow 2 Fe_(s) + Al_2O_3(s) Liquid water freezing to become ice. Liquid water boiling to become water vapor. Sweat evaporating from your skin.

Explanation / Answer

a state function in thermodynamics have a unique vakue for each given state of a system

The state functions are

i) Temperature of ice cube

ii) internal energy of a system

iv) the volume of an aerosol can

exothermic reactions- heat is released from the products and raises the temperature of the sorroundings.

endothermic reactions- heat is taken from the sorrounding and the sorrounding temperature decreases.

i) liquid water freezing to become ice- exothermic

ii) liquid water boiling to become water vapour- endothermic

iii) sweat evaporating from your skin- endothermic

iv) aluminium reaction with ferric oxide- exothermic

v) barium hydroxide with ammonium chloride - endothermic
