If the ice absorbed 350,000 joules in 5 minutes, then it absorbed energy 
at the rate of
   (350,000 joules) / (5 x 60 seconds)  =<em>  1,166-2/3 watts</em> .
Surely the ice cube didn't absorb every joule delivered to the cooking chamber, 
so the microwave oven's cooking power had to be significantly more than that.
        
             
        
        
        
That is the answer to your problem
 
        
        
        
Answer: A combination 0 degrees Celsius and 101.3 kPa or 1 atm correctly describes standard temperature and pressure.
Explanation:
The term standard temperature and pressure is also known as STP and it is most commonly used when we want to calculate the density of a gas. 
The term standard temperature means  Fahrenheit or
 Fahrenheit or  or 273 Kelvin. On the other hand, term standard pressure means 1 atmosheric pressure of a gas.
 or 273 Kelvin. On the other hand, term standard pressure means 1 atmosheric pressure of a gas.
Thus, we can conclude that a combination 0 degrees Celsius and 101.3 kPa or 1 atm correctly describes standard temperature and pressure.
 
        
             
        
        
        
The answer is B (The second one). I'm not sure though.
