Materials for the construction of an amusement park are being considered for the building of various rides and attractions at the park. Materials are being selected based on their specific heat and are listed in the table below. Material Specific Heat (J/(kg•K))
Iron 450
Aluminum 900
Steel 502
Glass 840
Plastic 2302

The formula that relates to energy change, mass, specific heat, and temperature change is:

Energy Change = Mass × Specific Heat × Temperature Change

The park engineers decided that a large, warm-water fish tank would be a great attraction at the park’s entrance. Based on the specific heats of plastic and glass, which material should they use to best warm the tank's water with heat from the sun? Explain your choice. How many times more energy would need to be transferred to the plastic for it to get as warm as the glass? Assume that the mass and the change in temperature are the same for both materials.
