Mars’s Perseverance Rover left the NASA’s space station with an ambient temperature of 54°F. During its journey in space between the Earth and Mars, it endured 27 K. Upon landing on the Martian surface, the Mars’s Perseverance Rover recorded a surface temperature of –63°C. a) What is the temperature difference between the Martian surface and the NASA’s space station’s ambient temperature in Rankine? b) What is the temperature difference in °C when the Mars’s Perseverance Rover exited the Earth from NASA’s space station and entered the vacuum of space?
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
