What is an investigation that is controlled? A controlled experiment is a scientific test that is directly manipulated by a scientist, in order to test a single variable at a time. This group is referred to as the control group, and allows for comparison with the other group, known as the experimental group. What are […]
Which organ system is responsible for obtaining oxygen?
Which organ system is responsible for obtaining oxygen? The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs. How […]

Which number is used in forced convection?
Which number is used in forced convection? The parameter of importance in forced convection is the Péclet number, which is the ratio of advection (movement by currents) and diffusion (movement from high to low concentrations) of heat. When the Peclet number is much greater than unity (1), advection dominates diffusion. What is the primary driving […]
What do radio waves visible light and gamma rays all have in common?
What do radio waves visible light and gamma rays all have in common? Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of […]

Is heat equal to change in enthalpy?
Is heat equal to change in enthalpy? At constant volume, the heat of reaction is equal to the change in the internal energy of the system. At constant pressure, the heat of reaction is equal to the enthalpy change of the system. What is flow and non flow process in thermodynamics? Non flow process: It […]
How many molecular orbitals will have an N value of 2?
How many molecular orbitals will have an N value of 2? Explanation: The atomic orbitals with an n value of 2 are the 2s orbital and the three 2p orbitals. When these four orbitals from one atom interact with four orbitals from another atom, they generate 8 molecular orbitals, half of which will be bonding […]
What is period of the wave?
Why is my diastolic pressure high?
Why is my diastolic pressure high? A: A high diastolic blood pressure (80 mm Hg or higher) that stays high over time means you have high blood pressure, or hypertension, even when systolic blood pressure is normal. Causes of diastolic high blood pressure include both lifestyle factors and genetics, but the disease is multifactorial. Why […]
