Answer:

1)The gas constant value is given by R = 8.3144598(48) J⋅mol^−1⋅K^−1.

2) Epidemics and pandemics have marked human history since time immemorial. Over the course of the last millennium, outbreaks such as plague, flu and Ebola have globally claimed millions of lives [1]. COVID-19 is the latest pandemic that, since its inception in China in November 2019, has redefined every facet of human life. As of June 2020, 470,000 lives have been lost, and there is a looming possibility of a still higher fatality in Brazil, the UK, USA and parts of Asia [2].

3)A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0)

4)COVID-19, Decision making, Exponential smoothing, Pandemic, Time series forecasting, Uncertainty

5)You can interpret the coefficient of determination (R²) as the proportion of variance in the dependent variable that is predicted by the statistical model.
