Answer:Water Only
Explanation:
Given
vessel is insulated therefore no heat can be added or removed i.e. heat exchange is zero
If hot water at  is mixed with cold water at
 is mixed with cold water at  then at equilibrium vessel contains only water and final temperature of water will be between
 then at equilibrium vessel contains only water and final temperature of water will be between  and
 and 
Heat released by hot water is equal to heat gain by cold water .
 
        
             
        
        
        
Because of the hint we can conclude what equation we need to solve this problem. We have power and duration that means that we need to express energy:
1 joule = 1watt * 1 second
or
E (energy) = P (power) * t (time duration)
E = 350 * 30 = 10500 joules.
        
             
        
        
        
Answer:
Explanation:
5 C = 278 K
25 C = 298 K
V1 / T1 = V2 / T2
1.5L / 278 K = V2 / 298 K
V2 = (1.5L * 298) / 278
V2 = 1.61 L
