Answer 1

Answer:

Explanation:

There is an equation specifically (no pun intended) for these types of questions:  ΔH=cmΔT  where  ΔH  is a change in enthalpy (energy) in joules,  c  is the specific heat capacity of the substance ( Jkg−1K−1 )in question,  m  is the mass of the substance being dealt with ( kg ) and  ΔT  is the change in temperature( °K ). Plugging in the values for your question we get

30,000=450∙5∙ΔT  

=>ΔT=30,0002250  

=>ΔT=13.3°K
