What statements are true about work and heat? (i) Work done on a system is negative. (ii) Work done by a system is negative. (iii) Positive heat is when energy is transferred into the system from the thermal reservoir. (iv) Negative heat is when energy is transferred into the system from the thermal reservoir. (v) Energy may be transferred into or out of a system as either work W or heat Q (a)( (i) & (iii) only (b) (ii) & (Iii) only (c) (i), (iii) & (v) only (d) (ii), (iv) & (v) only
