Malaria is a disease caused by a protozoan. this protozoan lives in the salivary glands of certain mosquitoes without causing the mosquito any harm or benefiting the mosquito. when a mosquito bites a human, some of these protozoa may be transferred to the human, causing a malarial infection. what type of interspecies interactions are the malaria protozoans exhibiting

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies.

Could someone me find the answer to this problem.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
