Calculate the change in temperature if a 25 gram piece of titanium absorbs 1205 Joules of heat energy and has a heat capacity of 0.345 J/g°C. If the starting temperature was 45°C, what was the final temperature?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
