Temperatures of four liquid substances are shown in the chart. which statement is best supported by the data in the chart? a) substance x will transfer thermal energy to substance y mainly through radiation if they are mixed. b) substance y will transfer thermal energy to substance z through conduction if they are mixed. c) substance x will transfer thermal energy to substance w through radiation if they are placed near each other. d) substance w will transfer thermal energy to substance x through conduction if they are mixed.

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?
