How do you derive kirchhoff's equation thermodynamics?
for the rxn A ---> B, where A is at temp T1 and B at temp T2 1) At constant pressure H1= HB - HA A first converts to B at temp T1 and reh temp rises to T2, thus the heat supplied for this change is Cp(T2-T1), Cp is the heat capacity of products. Hence the heat change will be given by H(path1)= Cp(T2-T1)+H1 2) first the temp of A is raised to T2. the heat supplied for this change is Cp'(T2-T1) , Cp' is the heat capacity of reactants. now A is changed to B with an enthalapy change of H2. H(path2)= Cp'(T2-T1)+H2. H(path1)=H(path2) H2-H1/T2-T1=Cp-Cp'
A ball is dropped from a window 64 feet high How long will it take to reach the ground?
The formula for position is x = 1/2at2. If we start at a distance of 40 feet, and gravity is 32 feet per second squared. So in this instance: 40 = 1/2 (32) t2 40 = 16 t2 40/16 = t2 2.5 = t2 t = 1.58 seconds
What variables stay the same in Charles law?
Well, pressure has to be kept constant and so does the mass of the gas with Charles's Law. Charles's Law--V1/T1=V2/T2--can be derived from the Combined Gas Law--V1xP1/T1=V2xP2/T2--by keeping the pressure constant which in turn cancels out the pressure in the Combined Gas Law leaving you with Charles's Law.
What is the formula for gay lussacs law?
Gay-Lussac's Law states that the pressure of a sample of gas at constant volume, is directly proportional to its temperature in Kelvin. The P's represent pressure, while the T's represent temperature in Kelvin. P1 / T1 = constant After the change in pressure and temperature, P2 / T2 = constant Combine the two equations: P1 / T1 = P2 / T2 When any three of the four quantities in the equation are known, the fourth can be calculated. For example, we've known P1, T1 and P2, the T2 can be: T2 = P2 x T1 / P1
A body travels with velocity v1 for time t1 second and with velocity v2 for time t2 second in the same direction find the average velocity of the body?
Average speed = (total distance) / (total time) = (v1t1 + v2t2) / (t1 + t2)
What does T2 and Flair hyperintensities mean in a MRI scan?
T2 FLAIR Hyperintensity is when hyperintensity is seen via FLAIR (Fluid Attenuated Inversion Recovery) during the T2, or spin-spin, relaxation cycle. This process helps nullify natural fluid signals in the body to find plaques and lesions in the brain. Hyperintensity describes areas of high intensity in the brain during an MRI.
What does it mean the brain parenchyma shows periventricular T2 hyperintensity and a few scattered subcortical foci of increased T2 and flair signal intensity in the frontal lobes that are nonspecifi?
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
What is T2 Hyperintensity in an elbow joint?
T2 hyperintesities is a medical term used to describe high intensity areas viewed on an MRI image. In the elbow, it basically means that there is reduced blood flow to that area of the body.
What is mild diffuse cerebral and cerebellum volume loss and T2 hyperintesnity within the periventricular white matter?
Mild diffuse cerebral and cerebellum volume loss and T2 hyperintensity within the periventricular white matter refers to a stroke. This can cause a slight decrease in the white matter of the brain.
What is T2 hyperintense mass involving the brainstem in a child?
A T2 weighted image, on a MRI, is not diagnostic, in and of itself. T2 hyperintensity could represent tumor, infarction, hemorrhage, or trauma, for instance. In the context of the clinical picture, the MRI is extremely helpful. If there has been no trauma, then the location and appearance of the T2 hyperintensity can point to a vascular cause versus a space-occupying lesion. The clinical course of the patient will cinch the diagnosis, when combined with the MRI findings - in cases such as these. In the case of a mass in the brainstem of a child, the most common cause would be that of a brainstem glioma. These account for anywhere between 10-20% of all brain tumors in children. However, this is not the only possibility (see above).
What is Two punctate foci of T2 hyperintensity in the subcortical white matter of the lateral anterior left frontal lobe?
Can hyponatremia cause white matter suggestive of minimal chronic microvascular ischemic change. The grey-white differentiation is maintained. minimal chronic microvascular ischemic on a brain scan?
What does t2 mean?
Terminator 2 it's possible it could mean something else as well but when ever I hear t2 it means Terminator 2
What is foci of T2 hyperintensity in the subcortical and periventricular white matter?
This phrase is a statement that would be used by a radiologist when reviewing the results from a MRI. Breaking down the phrase by individual parts:T2 - An indication of the type of scan that was done. In a T2-weighted scan, areas that are fluid-filled appear bright, while areas that are fatty appear dark. A T1 scan would show the opposite results.Hyperintensity - An indication of a bright region on the scan.Foci of T2 Hyperintensity, therefore, means "focal points, or concise areas, of very bright spots."Subcortical and periventricular white matter - These are locations within the brain. Regions of the brain are categorized by color (white matter or grey matter) and location (cortical, or related to the cortex, subcortical, or below the cortex, etc).The statement, therefore, means "white spots on a MRI scan at certain locations within the brain."This statement alone does not indicate any particular disease is present. It is a piece of information that a neurologist would use to help determine whether or not someone had a certain disease or condition. There are many conditions or diseases which can cause white spots on the brain; only a neurologist can sort through the possibilities and determine what caused these white spots.
What is a T2 hyperintense foci?
Type your answer here... it is a T2 hyperintense foci
A sample of air has a volume of 140ml at 67degrees Celsius At what temperature will its volume be 50ml at constant pressure?
V1/T1 = V2/T2 Where temperature must be in Kelvins 67C + 273 = 340 K So 140/340 = 50/T2 Find T2 340/140(50) = T2 T2 = 121 K or -152C
T2?
Air
What are the fingerings for g major scale on the double french horn?
If you start on the G on the second line on the staff and then go to the G above the staff, the fingerings go like this: 0-T12-T2-T0-T12-T2-T2-T0-T2-T2-T12-T0-T2-T12-0 (G, A, B, C, D, E, F#, G, F#, E, D, C, B, A, G)
