So you escaped the fate of wrapping hamburgers. The next step is to continue proving that you know dimensional analysis (it’s never too late for the hamburger people to come get you!) The great thing about dimensional analysis is that sometimes you can solve problems without equations. Here is such a case: a. All matter has a property called a specific heat capacity. For silver, this specific heat capacity is 0.24 J/°C · g.

Thermochemistry Using specific heat capacity to find heat Calculate the energy required to heat 0.70 kg of silver from -3.2 °C to 4.4 °C. Assume the specific heat capacity of silver under these conditions is -1 0.235 J.g¹·K ¹. Round your answer to 2 significant digits. x10 μ ☑ 0/3

Together, a pure gold ring and a pure titanium ring have a mass of 15.07 g. Both rings are heated to 94.90 °C and dropped into 13.0 mL of water at 16.80 °C. The water and the rings reach thermal equilibrium at a temperature of 24.20 °C. The density of water is 0.998 g/mL... The specific heat capacity of water is 4.18, the specific heat capacity of gold is 0.129 and the specific heat capacity of titanium is 0.544 Calculate the mass of each ring. mass of gold ring: mass of titanium ring: 50 60
