if statement with vector

Hello MATLAB community,
Everything was just working when temps was a scalar; however, I couldn't figure out why my code is not giving me 3 corresponding results for the vector temps. I am expecting 3 answers such that -1 is solid, 1 is liquid and 101 is gas.
Thank you.
temps = [-1 1 101];
F = 9/5 .* temps + 32;
if F <= 32
disp(['The Fahrenheit temperature is ', num2str(F)])
disp('solid')
elseif F > 212
disp(['The Fahrenheit temperature is ',num2str(F)])
disp('gas')
elseif F < 212 && F > 32
disp(['The Fahrenheit temperature is ',num2str(F)])
disp('liquid')
end

You are checking all values in the if conditioning, it gives pass condition if and only of all values are true, to avoid your situation use for loop to check each value of F
temps = [-1 1 101];
F = 9/5 .* temps + 32;
for ii=1:length(F)
if F(ii) <= 32
disp(['The Fahrenheit temperature is ', num2str(F(ii))])
disp('solid')
elseif F(ii) > 212
disp(['The Fahrenheit temperature is ',num2str(F(ii))])
disp('gas')
elseif F(ii) > 32 & F(ii)< 212
disp(['The Fahrenheit temperature is ',num2str(F(ii))])
disp('liquid')
end
end
