What are the factors that affect critical micelle concentration?
There are several factors affecting the CMC point of a surfactant. These include the amphiphile chain length, dissolved salts, the structure of the head group, temperature, the structure of the alkyl chain and polar additives.
What are the factors affecting student academic performance?
Students’ academic performance is affected by several factors which include students’ learning skills, parental background, peer influence, teachers’ quality, learning infrastructure among others.
What are 2 factors that affect academic performance?
There are two types of factors that affect the students’ academic performance. These are internal and external classroom factors and these factors strongly affect the students’ performance.
What are the factors that affect modular learning?
7 Important Factors that May Affect the Learning Process
- Intellectual factor: The term refers to the individual mental level.
- Learning factors:
- Physical factors:
- Mental factors:
- Emotional and social factors:
- Teacher’s Personality:
- Environmental factor:
What is meant by critical micelle concentration?
The CMC (critical micelle concentration) is the concentration of a surfactant in a bulk phase, above which aggregates of surfactant molecules, so-called micelles, start to form. The CMC is an important characteristic for surfactants.
What conditions influence micelle formation?
Micelles form only when the concentration of surfactant is greater than the critical micelle concentration (CMC), and the temperature of the system is greater than the critical micelle temperature, or Krafft temperature.
What are the factors that affect the academic performance of students in online learning?
Findings indicated that online learner participation and patterns of participation were influenced by the following factors: technology and interface characteristics, content-area experience, student roles and instructional tasks, and information overload. There may be a reciprocal relationship among these factors.
What are the challenges facing academic performance?
Academic concerns, which might include issues such as learning difficulties or disabilities, underachievement, lack of attention from teachers, and bullying, affect a number of students throughout their academic careers, from elementary school to college.
How modular distance learning affects academic performance?
Based on the result, the study revealed that students’ perceptions agreed on using modular distance learning approach (MDLA). It had also a positive effect to students’ performance in which students performed very satisfactory in Mathematics which means they had good quality performance.
How does modular learning affects the academic performance of the students?
Conclusions showed that there were significant differences between modular and traditional in general comprehension of students’. Findings depicted that students taught through modular approach gained higher mean score in teacher made general comprehension-based test than students taught through traditional approach.
What happens below critical micelle concentration?
Below the CMC the surface tension decreases with increasing surfactant concentration as the number of surfactants at the interface increases. Above the CMC, in contrast, the surface tension of the solution is constant because the interfacial surfactant concentration does not change any more.
What is CMC in chemistry class 12?
Critical micelle concentration (CMC) – The concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles, is known as critical micelle concentration. It is an important characteristic of a surfactant.
