Suppose
u has units degree Celsius ({}^\circ C), time t is in seconds (s), x is in centemeters (cm).
We have the equation u_t = \alpha^2 u_{xx} - \nu u_x

What are the units ofu_t :

cm / s

{}^\circ C / s

cm{}^2 / s

g / cm{}^3

{}^\circ C / cm{}^2

s / {}^\circ C

cm / s{}^2

{}^\circ C-s

What are the units of\nu :

cm{}^2 / s

cm / s

{}^\circ C / s

s / {}^\circ C

g / cm{}^3

{}^\circ C / cm{}^2

cm / s{}^2

{}^\circ C-s

What are the units of\alpha^2

{}^\circ C / s

g / cm{}^3
