Answer:


Q=2091J=2.091kJ

Step-by-step explanation:

Hello,

In this case, the formula we use to compute the heat Q by increasing the temperature, in terms of the mass and the heat capacity is:


Q=mCp(T_2-T_1)

Titanium's heat capacity is 0.544284 J/g°C, thus, the for such temperature increase, the heat results positive as shown below:


Q=22.6g*0.544284(J)/(g^oC)*(1590^oC-1420^oC) \\\\Q=2091J=2.091kJ

Best regards.
