What is the first step in the rock cycle turning metamorphic and igneous rocks into sedimentary rocks?

When using the scientist method, which step comes last?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).

What will happen in a hybrid vehicle if current flow becomes too high due to a short?
